How does Flextron work?

FLEXTRON enhances stability, energy return, and support on uneven, technical terrain. The TPU midsole acts like a springboard for added rebound, while the shank provides stability to keep you balanced during scrambles. High side walls wrap the heel and midfoot for secure, flexible support, reducing strain for confident movement on demanding approaches.

Mountain Performance Fit

Designed for moments where precision is paramount, our Mountain Performance Fit wraps closely around the foot, especially at the heel and arch, to minimize internal movement and deliver secure, controlled steps on technical ground. Supple materials mold over time for a precise hold that supports confident movement on demanding terrain.
