COMFORT, TIMES TWO. The NikeLab Free Huarache Carnivore Men's Shoe updates a classic track shoe with a Nike Free 5.0 outsole for incredible flexibility and lightweight comfort. The innovative, versatile design allows you to remove the outer bootie to create two looks in one a sandal-like shoe and a slipper-like bootie that wraps your foot. Durable Outer Layer The outer layer features an upper made from premium leather for durable comfort. Cutouts in the leather help keep your foot cool and the shoe lightweight, and rubber straps with hook-and-eye loops provide a snug, adjustable fit. Enhanced Flexibility Deep flex grooves on the outer layer are hot-knife cut into the outsole, allowing your foot to move naturally in every direction. Slipper-Like Comfort The interior bootie features layered mesh and perforations for ventilation that helps your foot stay cool, and texture for light traction. Its glove-like fit provides lightweight yet sturdy support.
