The Reebok CrossFit Nanossage is a training shoe built for a natural feel. The ultra soft cushioned C42 Foam with a Foam Roll construction decompresses the foot and allows for the most natural splay. A 0 drop outsole enables you to get to the barefoot state, and the forefoot and heel foam pods offer excellent cushioning and shock absorption. A PlayDry lining in the midsole helps wick away moisture so your feet stay fresh, while full-length low-profile EVA offers cushioning. A Dual Web Pull entry and slip-on construction gives you easy on and off. High Density Printed Toe cap increases durability and provides modest protection. Poly Elastane gives you a perfect fit. This shoe is machine washable.
