Regardless of realizing higher, most climbers put on sneakers two sizes too small. Athos, a Barcelona-based firm, is hoping to alter that with the world’s first 3D-printed climbing sneakers, promising a bespoke match with the assistance of digital scans.
Over the course of two years, what started as a Grasp’s undertaking for the Elisava College of Design and Engineering has become a startup. 4 college students—Emili S. Taixés, Romina Milesi, Carla Barrientos, and Mar Amengual—had all dabbled in climbing, however their concept to create 3D-printed sneakers got here to a head when the group took a take a look at a extra skilled pal’s ft and noticed that the consequences of carrying climbing sneakers for years weren’t fairly.
“We noticed that his ft have been deformed, and we have been like, ‘What’s that?’” Amengual instructed Climbing over a video chat. The scholars mentioned they realized how problematic down-sizing might be. They discovered a examine, revealed in 2013 within the World Journal of Orthopedics, stating that 80 to 90 p.c of climbers reported ache whereas carrying climbing sneakers. The paper mentioned how too small of sneakers results in nail-bed infections, overstrain accidents, and “the event of a hallux valgus deformity”—a.okay.a bunions.
“We have been like, ‘Nicely, we prefer to climb, however we don’t need our ft to be hurting!’”
Current advances in know-how have each improved the usual of climbing sneakers and decreased the necessity for downsizing. That mentioned, most climbers nonetheless measurement down so for higher match and for efficiency advantages. Whereas a bit foot ache feels to some like a worthy value to pay, Athos asks an admirable query: Is there a greater strategy to make sneakers?
The way it Works
Athos, presently solely working domestically, begins by taking digital scans of the client’s ft. They apply these dimensions to their customary sample, which has developed over many iterations to optimize end-feel and to lower manufacturing processes. Every shoe is designed to be next-to-skin—no downsizing.
Athos makes use of vegan supplies: thermoplastic polyurethane, or TPU; polyester (for the laces); and Vibram rubber. TPU is understood to be abrasion resistant and is one hundred pc recyclable and biodegradable. In keeping with Amengual, it received’t stretch, both. Total, Athos’s 3D printing course of reduces the usual manufacturing procedures for shoe-making by 70 p.c.
The TPU varies in thickness throughout the shoe to create stress the place conventional sneakers might need slingshot rands. They look like pretty gentle, with a slight downturn, and maybe splendid for beginner-level climbers. Whereas climbers can’t make alterations to the shoe sample or stiffness, they will decide the design proven on the surface of the shoe, and even get their title inscribed.
Athos continues to be presently in a beta part of testing; Barcelona climbers ought to obtain the primary spherical of publicly launched sneakers quickly. Costs, says Amengual, are TBD. Ultimately, the startup hopes to be worldwide, and we at Climbing hope to check a pair when the day arrives.
Finally, Athos goals to alter the way in which climbers take into consideration their ft. “Each foot is exclusive,” says Amengual. “Our goal is to offer each climber the proper climbing shoe to allow them to benefit from the climbing expertise a bit extra.”
