Inspired by our expertise in elite-level base layers, the SkinKnit® upper wraps the foot and syncs with the TerraSkin® sock for comfort and support. The patented SpeedFrame® construction creates a stable wrap around the soft core of the shoe, integrating upper and midsole into one stable unit. The design allows vertical cushioning while stabilizing horizontally for confident performance on uneven ground. The SpinWeave® outsole flexes and adapts to uneven ground. Independent testing shows it increases ground contact by up to 27% versus other premium trail shoes. Add Vibram® MegaGrip traction and you have serious hold. So you feel invincible on the downhill.
