The Xero Shoes HFS II is a lightweight road-running barefoot shoe that delivers grip, comfort and natural movement. A tire-tread-inspired FeelTrue rubber outsole provides traction on the road and off, while a thin BareFoam layer wraps cup-like around the upper for an extra layer of protection and a familiar look. The breathable, moisture-wicking upper hugs the foot with welded accents, and huarache-inspired straps hide beneath protective material to lock you in. Zero-drop, wider toe box, and 8.3 oz light (men's 9) — backed by Xero's 5,000-mile sole warranty.
