A climbing shoe is a specialized type of footwear designed for rock climbing. Typical climbing shoes have a tight fit, an asymmetrical downturn, and a sticky rubber sole with an extended rubber rand to the heel and the toe. [1] Different types of shoes can be better suited for different levels of technique and routes. [2]
Modern climbing shoes use carefully crafted multi-piece patterns to conform very closely to the wearer's feet. More traditional climbing shoes tend to be stiff, but modern performance oriented models are often quite soft with a flexible midsole. [3]
A typical climbing shoe is made out of 9 parts: heel loops, lining, tongue tab, tongue, closure system, upper, toe box, rand, and heel. [1]
Leather is the most common upper material, but other materials such as fabric and synthetic leather are also used. [1] [4] The climbing rubber used for soles was developed specifically for rock climbing. [5] [6] The two types of leather used in shoe construction are unlined leather and lined leather. [2] [3] Unlined leather stretches more than its lined counterpart. [1] [2] As such, lined leather is used in areas where stretching is not desired, and occurs the most. [1] Unlined leather is often used on the tongue and tongue tab of the shoe where stretching is desired. [2] Synthetic materials are more rigid and provide ventilation for the shoe; they are often used in the liner, heel loops, and the closure system. [1]
The soles of climbing shoes are made out of special rubber composites. These rubber composites differ depending on the desired stickiness, durability, and softness. [1] [7] [8] Climbing shoes have rubber that are unique to the type of shoe as it molds onto the holds of a wall. There is a tradeoff between stickiness of a rubber and its durability. [5] Stickier shoes provide better performance for climbers, but are worn out quicker. [5] [3]
Modern climbing shoes come in different closure systems that allow the wearer to adjust the tightness of the shoe. [1]
Lace-up shoes use a traditional lace, like those on sneakers, that reaches the rand of the shoe. Lace-ups provide climbers with the most adjustability in the shoe's tightness. According to REI, a climber wearing lace-up shoes can loosen the shoe for walk-off routes or tighten the laces to complete a harder route. [2]
Velcro shoes will often have one or two Velcro straps that allow for the adjustment of tightness. Velcro allows for quicker but less precise adjustments than laced shoes. They are commonly used in indoor-climbing environments because they are easier to take on and off. [1] [2]
Slip-on shoes do not have any form of adjustable closure, allowing the user to fit their shoes into tighter fitting spaces. They need to be fitted properly in order to prevent the feet from moving inside the shoe. A benefit of this close fit is a higher sensitivity to the climb, allowing the wearer of the shoe to use smaller holds for their feet. [4] [2] [9]
Climbing shoes are typically made with one of two types of noses: pointed or rounded. [4] [10]
Pointed shoes can make it easier for climbers to stand on smaller holds. [4] [10]
Rounded shoes allow all toes to reach the front of the shoe more easily, granting the climber more power when pushing off the wall. [4]
Modern climbing shoes are typically subdivided into three different profiles based on their shape: neutral, moderate, and aggressive. [10]
Neutral shoes, similar to everyday sneakers, feature a flatter outer sole that allows the foot to rest flat during use. According to REI, this style of shoe is best fitted for beginner climbers because of comfortability. More experienced climbers may also use neutral shoes to climb longer routes. [2] [10]
Slightly more downturned than the neutral shoe, moderate shoes have a cambered (curved) toe box. They typically have a thinner sole and stickier rubber than neutral shoes. This enables climbers to climb different types of routes, including slab, crack, slight overhangs, and multi-pitch. [2] [10]
Aggressive shoes feature a stronger downturn than moderate shoes. This style of shoe is often the most painful to wear for climbers due to its strong curve and heel tension. According to REI, they are shaped asymmetrically to allow for climbers to place greater weight on their big toe in footwork techniques. [2] [10] Aggressive shoes, similar to moderate shoes, have thin soles and sticky rubber, giving climbers greater sensitivity in their feet. [10] [5]
Climbing shoes fit very closely to support the foot and allow the climber to use small footholds effectively. Most climbers forgo socks in order to achieve a more precise fit. Climbers will typically wear shoes in a way that sometimes uncomfortably constricts their feet. [11] [12] A smaller size allows the toes to be at the front of the shoe, preventing it from shifting inside the shoe, and can allow the climber to generate more force. As a result of their tightness, most climbing shoes, particularly the more aggressive or technical styles, are uncomfortable when properly fitted.
Because pointed shoes may cause the toes to not reach the front of the shoe, this can lead to the use of smaller shoes. Depending on the material of the upper, the shoes may can stretch up to an additional two sizes, which can encourage climbers to buy shoes that are even smaller than they typically would. [13] The tight fit of climbing shoes have raised concerns about the impact on climbers' feet. Foot pain or discomfort as a result of tight shoes is a common complaint among climbers. [12] [14] Given their stiff nature, the foot can be compressed while wearing climbing shoes, and chronic injuries and deformities, like hallux valgus and achilles tendinitis, can occur with long-term usage of overly-tight shoes. [3] [13] [12]
The modern climbing shoe's features leverage a climber's ability to use their feet more technically.
Edging is a footwork technique where climbers rely on their toes to step on smaller surfaces. Shoes that are downturned aggressively and have a pointed toe allow the climber to utilize their feet on smaller foot holds. The stiffer the sole of the shoe, the more pressure a climber is able to put on their toes. [15]
Smearing is when a climber uses the sole of their shoe to walk on a wall or a flat surface without any footholds. Shoes with a more sensitive sole made of thinner rubber allow for the climber to have more flexibility in their feet and not use footholds. [15]
A toe hook is when the climber utilizes the rubber on the toe of their shoe to hook their toe onto a hold. A heel hook is when the climber utilizes the rubber on the heel of their shoe to hook their heel onto a hold. The rubber allows for greater frictional support and adherence between the shoe and the hold. [15] [16]
Early rock climbers used heavy-soled mountaineering boots studded with metal cleats and hobnails. An advance on this for dry rock, were boots with Vibram soles, with a pattern of rubber studs developed by Vitale Bramani in Italy in the 1930s. [17] In postwar Britain, a new generation of climbers like Joe Brown began to climb harder routes wearing plimsolls (rubber-soled canvas sneakers), [18] sometimes with woolen socks over them to improve grip. [19] Pierre Allain was an enthusiastic French rock climber who experimented with hard composite rubber-soled canvas boots; by the late 1950s, his "PA" boots were being used by climbers worldwide. Fellow French climber Edmond Bourdonneau later introduced "EB" boots in 1950 after purchasing Pierre's company, [20] which had softer rubber soles and became very popular in the 1960 and 1970s. In 1982 Boreal, the Spanish company located in Villena, produced the "Firé" style of shoe with a revolutionary sticky rubber sole. [17]
A climbing shoe will deteriorate at different rates depending on the habits of the climber wearing it. [9] The sole may wear down or delaminate from the rand, and important seams can fray which endangers the structural integrity of the shoe. [9] A study done on consumer practices suggests that users will either repair or purchase new objects when faced with worn materials that affect service. [9] It was found that consumers tend to choose to repair products when the practice allows them to maintain a habit, such as having broken-in shoes that the consumer would prefer to wear instead of a new pair. [21] When climbing shoes experience wear, especially damage that prevents use, they can be sent to a resoler. [9] The resoler can perform repairs such as a half-resole or a re-rand to mend the shoes. [9] A resole will not change how the shoe fits or is shaped, which allows the consumer to maintain their habits. [9] [21] A re-rand is required for more damaged shoes, which can impact the shoe's shape. [9] If a shoe that experiences wear is left unrepaired for too long, it may reach a point where it can no longer be mended and a new pair must be purchased. [9]
A vast majority of climbers choose to use tight climbing shoes since less restrictive shoes leave room for the foot to slip around inside the shoe and can make it harder for individuals to gain stability on smaller climbing surfaces. [1] [12] Smaller climbing shoes are especially common among more elite climbers. [12] Tighter shoes can help improve a climber's ability, so many climbers are willing to compromise their foot comfort. [12] The climbing culture around smaller shoes has garnered attention regarding the health of climbers’ feet. The smaller fit has been shown to stunt bone growth in younger climbers and have lasting injuries and deformities. [12] [22] The injuries and health complications related to tight climbing shoes have also prompted research into developing more appropriate climbing shoes. One group of researchers has developed a climbing shoe prototype that molds to the foot for a more natural fit with features that accommodate the variance in foot width among climbers. [13] The findings from this prototype show that different shoe designs can help reduce the risk of injury while maintaining climbers’ ability level. [13]
Rubber-derived chemicals (RDCs) are chemicals that may be harmful to humans when ingested and can be found in high concentrations in the rubber soles of climbing shoes. [13] The rubber additives are released into the air when the rubber wears down through use. A study has found that there are higher levels of RDCs present in indoor climbing gyms compared to other environments where climbing shoes are not typically worn. [23] Adults who frequent these gyms inhale more RDCs than the average person, and this raises potential health concerns about rubber additive levels in climbing shoes’ soles. [23]
A shoe is an item of footwear intended to protect and comfort the human foot. Though the human foot can adapt to varied terrains and climate conditions, it is vulnerable, and shoes provide protection. Form was originally tied to function, but over time, shoes also became fashion items. Some shoes are worn as safety equipment, such as steel-toe boots, which are required footwear at industrial worksites.
Footwear refers to garments worn on the feet, which typically serve the purpose of protection against adversities of the environment such as wear from rough ground; stability on slippery ground; and temperature.
Ski boots are footwear used in skiing to provide a way to attach the skier to skis using ski bindings. The ski/boot/binding combination is used to effectively transmit control inputs from the skier's legs to the snow.
A crampon is a traction device attached to footwear to improve mobility on snow and ice during ice climbing. Besides ice climbing, crampons are also used for secure travel on snow and ice, such as crossing glaciers, snowfields and icefields, ascending snow slopes, and scaling ice-covered rock.
Clogs are a type of footwear that has a thick, rigid sole typically made of wood, although in American English, shoes with rigid soles made of other materials are also called clogs.
A pointe shoe, also referred to as a ballet shoe, is a type of shoe worn by ballet dancers when performing pointe work. Pointe shoes were conceived in response to the desire for dancers to appear weightless and sylph-like and have evolved to enable dancers to dance en pointe for extended periods of time. They are manufactured in a variety of colors, most commonly in shades of light pink.
Thigh-high boots, known also as thigh-length boots or simply thigh boots, are boots that extend above the knees to at least mid-thigh. Other terms for this footwear include over-the-knee boots, a name originally used for 15th century riding boots for men. These are sometimes called pirate boots, especially when cuffed. Over-the-knee boots are sometimes abbreviated to OTK boots. Lengths vary from reaching just over the knee to reaching almost to the crotch.
Sandals are an open type of shoe, consisting of a sole held to the wearer's foot by straps going over the instep and around the ankle. Sandals can also have a heel. While the distinction between sandals and other types of footwear can sometimes be blurry, the common understanding is that a sandal leaves all or most of the foot exposed. People may choose to wear sandals for several reasons, among them comfort in warm weather, economy, and as a fashion choice. Usually, people wear sandals in warmer climates or during warmer parts of the year in order to keep their feet cool and dry. The risk of developing athlete's foot is lower than with enclosed shoes, and the wearing of sandals may be part of the treatment regimen for such an infection.
Motorcycle boots are associated with motorcycle riders and range from above ankle to below knee boots. They have an outside of a typical boot but a low heel to control the motorcycle. To improve motorcycle safety, motorcycle boots are generally made from a thick, heavy leather and may include energy absorbing and load spreading padding, metal, plastic and/or composite materials to protect the motorcycle rider's feet, ankles and legs in an accident. For use in wet weather, some boots have a waterproof membrane lining such as Gore-Tex or SympaTex.
Jump boots are a type of combat boot designed for paratroopers featuring calf-length lacing and rigid toe caps. The style was developed in many countries simultaneously with the adoption of airborne infantry forces during World War II. Modern jump boots are earned in some countries and therefore have become a mark of achievement and distinction, mainly worn as dress and parade boots. The uppers are generally made of smooth black leather with toe-caps and heel counters that accept a high polish. It is also a paratrooper tradition to lace jump boots in a ladder or cobweb style which increases ankle support during a parachute jump.
Track spikes, or just spikes, are a type of footwear featuring protruding spikes on the soles used by athletes when racing on the track. Some spikes are designed for longer-term training on tracks, but generally the shoes are used for racing. The term "spikes" can also refer to track shoes featuring such protrusions, though these are technically called pins. Spikes are similar to studs, which are used for team sports, although generally smaller and with a sharp point.
Hiking (walking) boots are footwear specifically designed for protecting the feet and ankles during outdoor walking activities such as hiking. They are one of the most important items of hiking gear since their quality and durability can determine a hiker's ability to walk long distances without injury. Hiking boots are constructed to provide comfort for walking considerable distances over rough terrain. Boots that protect the hiker's feet and heel are recommended. Hiking boots give ankle support and are fairly stiff. A less popular alternative is to use light trainers with thin soles. Footwear should be neither too loose nor too tight, to help prevent blisters and sore feet. Hiking socks that wick sweat from the feet, provide warmth, and cushion the feet are recommended and a thin, inner sock may also help. Most hiking boots are also designed for other outdoor activities such as backpacking, climbing, mountaineering, and hunting.
The brogue is a style of low-heeled shoe or boot traditionally characterised by multiple-piece, sturdy leather uppers with decorative perforations and serration along the pieces' visible edges.
Cycling shoes are shoes purpose-built for cycling. There are a variety of designs depending on the type and intensity of the cycling for which they are intended. Key features include rigidity, for more-efficient transfer of power from the cyclist to the pedals, weight, a method of attaching the shoe firmly to the pedal and adaptability for use on and off the bicycle. Most high-performance cycling shoes can be adjusted while in use, via a quick-adjusting system that has largely replaced laces.
The ballet boot is a contemporary style of fetish footwear that merges the look of the pointe shoe with a high heel. The idea is to restrict the wearer's feet almost en pointe, like those of a ballerina, with the aid of long, slender heels. When upright, the feet are held nearly vertical by the shoe, thus putting nearly all of the body's weight on the tips of the toes. However, a properly tight fit will hold the shoe to the wearer's instep and heel, thereby reducing the weight on the wearer's toes.
A moccasin is a shoe, made of deerskin or other soft leather, consisting of a sole and sides made of one piece of leather, stitched together at the top, and sometimes with a vamp. The sole is soft and flexible and the upper part often is adorned with embroidery or beading. Though sometimes worn inside, it is chiefly intended for outdoor use.
A dress shoe is a shoe to be worn at smart casual or more formal events. A dress shoe is typically contrasted to an athletic shoe.
Ghillies are specially designed shoes used for several types of dance. They are soft shoes, similar to ballet shoes. They are used by women in Irish dance, by men and women in Scottish country dance, and by men and women in Scottish highland dance.
Slab climbing is a type of rock climbing where the rock face is at an angle less steep than vertical. It is characterized by balance- and friction-dependent moves on very small holds. It is often not leadable, or climbable from the ground up, unless it has pre-drilled bolts to protect the climb, making most slab climbs either top rope climbing or sport climbing. Special techniques such as smearing are necessary to climb slab. It is a type of face climbing and is distinctly different from crack climbing. Slab climbing is a relatively new area of climbing, having become more popular in the last 30 years, and some of the highest graded routes are currently being realized.
The toe box is the section of footwear that surrounds the toes on closed-toe shoes. Toe boxes that are too tight can cause injuries and foot deformities, whereas wider toe boxes may be used to treat or prevent common foot conditions such as broken toes, bunions, and Morton's neuroma. Toe boxes come in a variety of shapes and styles of construction, some of which are a matter of fashion, and some of which are designed for specialized functions.
