The Nike Free x metcon Men's Training Shoe combines the lightweight flexibility of Nike Free with the durability and stability of Nike metcon shoes. This makes it ideal for short runs, boot camps, strength training and the WOD. The lightweight mesh is particularly durable in high-stress areas, stable and flexible. Rubber wraps up the sides of the shoe to help resist abrasion during rope climbs. Deep grooves along the sole allow the shoe to bend and expand in all directions. This means an incredibly natural, lightweight feel as you train. The midsole is made of soft foam in a firmer foam carrier. This gives you comfortable cushioning where you need it and stability for heavy weights.
