Cinq ans. C’est environ le temps qu’il a fallu aux designers de BD pour créer notre gamme unique de chaussons d’escalade. Au début, ils n’en disaient mot à personne. Pas même à leurs responsables.

“Plutôt que d’attendre que quelqu’un dise “bon, allons-y, fabriquons des chaussons”, nous avons commencé à regarder cela plus près à notre manière” confie le vice-président du Design Kasey Jarvis.

Le raisonnement était simple. En tant que grimpeurs, nous voulons fabriquer le meilleur chausson d’escalade. Et d’une certaine façon, nous le savons par expérience, les chaussons d’escalade sont les seuls éléments de matériel qui comptent vraiment en matière de performance.

“La magnésie et les chaussons influent directement sur nos performances,” précise Kasey.

Voilà pourquoi les designers se sont acharnés. Kasey a fait équipe avec Linh Nguyen, designer de chausson depuis longtemps et pointure dans le monde du matériel d’escalade ayant collaboré avec Chris Sharma et Evolv par le passé et actuellement concepteur technique chez BD — puis ils se sont mis au travail en dehors des heures de bureau. Lorsque les responsables ont vu que Kasey et ses collègues dessinaient lors leurs rencontres « clandestines », ils ont compris que l’équipe préparait quelque chose.

“Nous voulions réellement créer un design de chausson unique du début jusqu’à la fin” affirme Kasey.

Cependant cela signifiait beaucoup plus de travail, et pour les designers les dernières années avaient déjà été difficiles et chargées, rappelle Kasey.


Climbing shoes have long followed a traditional recipe. The materials have largely remained unchanged for decades. Leather—synthetic leather if it’s cheaper—and rubber. However, when Kasey and Linh began to meet with manufacturers of the old guard, their answer to “why” they continue to follow this recipe was because they’ve always done it that way.

Simply put, following the usual formula is not the preferred BD method. Kasey and Linh began the design process and immediately questioned everything. And what they found was that they could bring new, cutting-edge materials into a traditional world of manufacturing.

“We’re not winning by cooking with the same ingredients,” explains Kasey. “We’re winning by changing the recipe.”


When Kasey first started at BD over seven years ago he was amazed at how all the engineers and designers had intimate knowledge of their materials. And Kasey was no slouch himself, coming from a background with General Motors and Nike.

“I remember being shocked how everyone had a baseline level of knowledge about metal—whether it was forging, stamping, casting, swaging, brazing, heat treating—all the things that you do to work metal.”

And when the team began focusing on climbing shoes, they dove in head-first.

“It’s a very engineered approach,” explains Kasey. “Usually, nobody wants to go that deep into something, but that’s the Black Diamond way.”


Applying their metal background to the shoe world, the team’s first big break-through was inspired by the way BD carabiners are forged.

“Instead of just die-cutting a sheet of rubber, we’re taking raw material and essentially molding it into a controlled shape, where we control the geometry, the recipe for the rubber, the heat, pressure, and thickness,” says Kasey. “Basically, we’re pulling all the levers, and you have to be way more ‘in the weeds’ for that.”

The benefit of this approach to climbing shoe rubber is that each mold is individually created to fit together—unlike the trace, trim and hand-grind method. This allows us to vary the weight, thickness and consistency of each mold to enhance our rubber’s overall comfort, durability and performance.

Getting in the weeds with rubber technology is only half of the story. Kasey and crew also began re-thinking the way we approach the shoe’s upper materials.

“We’re doing the same thing with soft goods,” he says. “We’re exploring the way they’re woven, the way the yarns are extruded, and the way they’re knit.”

What the team discovered is an “Engineered Knit” upper that provides stretch where you need it, support where it matters, and exceptional breathability. The process to create this knit material once again relies on having complete and total control of the manufacturing process.

“We’re literally controlling the tension of the knit machine to get the durability of the knit to where we think it needs to be, to get it to hold the right shape, and to have the right openings for breathability. We’re in control of all the variables,” says Kasey.

Our Engineered Knit Technology is featured throughout our shoe line, beginning with the Momentum—which utilizes it exclusively as a complete, breathable upper optimized for gym climbing. The Aspect also features our unique knit on the shoe’s tongue for added comfort.

Thanks to a molded midsole, our shoes will hold their shape much longer than competitors’. And once again, this is an example of getting deep in the weeds and engineering the heck out of the shoes.

“Instead of just die-cutting out a piece of plastic that then gets sandwiched in the construction of the shoe, we’re 3D molding a plastic midsole that matches the shape of the last so that longer term, the shoe stays the same,” explains Kasey.

The midsoles are constructed with Pebax plastic, which Kasey believes has the best memory and keeps its shape. That’s why a high-quality ski boot is made of Pebax, he says.

“You can just rally them over and over and they will still recover,” Kasey explains.

That means over time, no matter how many hours you spend teching your way up slabs, running laps in the gym, or crimping on the boulders, your BD climbing shoes will retain their shape.

“We’re going to change the paradigm longer term,” says Kasey, “where people will buy a shoe, and they’ll be able to get the same benefit from it pretty much throughout its life, until you have to resole it.”

When asked what he likes most about BD’s new climbing shoes, Kasey boils it down to one succinct answer.

“For me, they’re shoes that give you confidence. And that’s really what matters.”
