So iLL Stay

The So iLL Stay is a very soft, regular volume unisex climbing shoe for bouldering and route climbing. The shoe is crafted with precision and expertise, designed by Jae Jung with consultation from Fred Nicole. Built on an all-new, hand-shaped, downturned last, this shoe features a durable and comfortable unlined vegan microsuede upper. The performance single-strap closure with d-ring integration ensures an ultra-precise fit. The split outsole is equipped with high-performance Vibram XS Grip rubber, providing excellent durability and generous toe rubber coverage for all hooking needs. Stay's thinner rubber design enhances sensitivity and creates a larger contact patch for smearing on slab.
