Deckers X Lab K-ST 21 Sneaker
The experimental arm of the company behind Hoka, Teva, and more, Deckers X is focused on advanced footwear technologies. The K-ST 21 is a perfect example. It has an angled, swallowtail heel that helps transfer downward energy into forward momentum, helped along by a carbon plate in the midfoot that helps move that energy into the toe box. Meanwhile, a multi-material upper mixes Cordura ballistic nylon, Lycra in the tongue and toe box, and ultra-rugged, Kevlar-infused Matryx weave for a lock-down fit and extreme durability.
