Theory is the performance sneaker designed for a perfect fit to the new shapes of indoor climbing skins. The shoe is designed to release maximum strength and mobility while maintaining maximum sensitivity with any type of grip. With a new construction that uses the exclusive D-Tech™ (Dynamic Technology), the sole wraps around the shoe on the side, ensuring a complete absence of side edges, promoting dynamic support and expansion ability in the last hall cellar. The Vibram® XS-Grip2 sole with differentiated toe strength promotes grip and the lower heel allows maximum precision on the heel hooks.
