When I started rock climbing, I struggled to select a climbing shoe that would support me as I explored my newfound passion: I was told to get the tightest shoes I could squeeze my feet into to maximize performance, but this limited the amount of time I could spend on the wall without being in extreme pain. The alternative to this shoe was a very neutral shoe that didn’t perform nearly as well as the aggressive models but was far more comfortable to wear over longer periods. In short, I was faced with the dilemma of choosing comfort or performance, and at the time, I chose comfort. Being a more experienced climber now, I’m used to cramming my feet into downturned shoes, yet I can’t help but miss the comfortability I had in the neutral shoes I used to wear. 

More recently, as a climbing instructor and coach, I’ve noticed how climbing shoe design could better support the commonly used climbing techniques, such as toe and heel hooks while aiding in a comfortable fit. For example, the strongest part of the foot to toe-hook is the upper dorsal portion of the foot, but the enclosure systems always cover this area. Instead, relocating the enclosure systems to the sides of the shoe would allow for closer contact between the dorsal foot and the wall, and would perhaps provide better sinching at the heel cup, which is often baggy.

Modern climbing shoes often face tradeoffs when attempting to balance performance and comfort; however, I don’t believe this needs to be the case. By rethinking the relationship between fit and performance, and embracing how the two factors work in tandem with one another, I aim to design a climbing shoe that improves upon the industry standard. My shoe design will combine a slipper construction with a novel side-enclosure system to enhance performance while prioritizing comfort, rather than sacrificing it. Specifically, this shoe utilizes a sinch at the heel—rather than the tongue—to provide an aggressive, customizable fit. Not only does this design choice make room for a rubberized tongue that increases friction on the top of the foot for toe-hooks, but it also facilitates an elastic slipper construction, enabling a skin-tight fit that is easy to quickly slip on and off of the foot.

Climbers often have to choose between wearing a shoe that is comfortable for extended periods or a shoe that allows them to perform at their limits. As a result, climbers often carry multiple pairs of shoes that serve different purposes, even though this practice doesn't compensate for specific deficiencies of a shoe when worn in isolation. A great example of this can be seen in the normalization of shoe breaks—or taking short breaks from wearing one’s shoes— when wearing aggressive or performance-oriented climbing shoes. When a climber prioritizes performance in their footwear choice, they still sacrifice comfortability, which detracts from their climbing experience, even if they have a more comfortable pair on hand. As a climber and designer, I see these experiences as the rationale for challenging existing climbing shoe designs. Furthermore, the fact that this dilemma still exists indicates that there is significant room for improvement within the design space of climbing shoes.

A typical climber may have one all-around climbing shoe, or several dedicated pairs to choose from, which can be broken down into three distinct construction types: Slipper, Velcro, and Lace-Up. Broadly, slipper-style shoes offer a comfortable toe box at the expense of a tailored heel cup, while velcro and lace-up constructions unnecessarily restrict the toe movement to better fit the heel. This issue can be explained by the fact that climbing shoes have traditionally employed enclosure systems influenced by conventional shoe designs, rather than pioneering enclosure systems specific to the needs of modern climbers. These enclosure systems achieve a tailored heel fit by over-tightening the fit of the shoe elsewhere on the foot. The use of these enclosure systems is inappropriate because unlike conventional shoes, which aim to avoid chafing or friction in the heel, climbing shoes generally require a precise heel that adheres to the foot with very little movement. Therefore, the proper solution to this issue is a climbing-specific enclosure system that isolates tension on the heel while allowing for comfort through mobility in the rest of the shoe.

Advancements in climbing shoe performance can be seen in minute tweaks to the three aforementioned construction types, however, major structural changes haven’t been made in recent years. One reason for this acceptance of current climbing shoe designs is that they generally work well, and making smaller edits to an existing construction is much less daunting and risky when compared to redesigning a completely new enclosure system. Moreover, when making significant changes to a widely accepted product, apprehension from consumers is a valid concern to have, especially given how flooded the climbing shoe market currently is.

The purpose of this project is to sharpen my design skills, learn how to 3D model and render in Modo, and gain more industry knowledge within the footwear market. Because of this, I have a fairly flexible timeframe to complete this project, and depending on the resources available at Nike, I hope to make several functional prototypes, though, at the very least, I expect to produce to-spec renders.

This multifaceted project is influenced by the outdoor sports industry—specifically the climbing industry—and the footwear industry, and should subsequently be of interest to both. I am particularly inspired by the branding, innovation in design, and aesthetics of Nike, Evolv, and La Sportiva, and expect to draw influences from these companies in the creation of my climbing shoe. This project, finally, appeals to the consumers of said products; climbers should especially invest interest in an improved climbing shoe.
