Built to keep you feeling light even when the weights are feeling heavy, the Nike Free X Metcon training shoes provide a lightweight fit with premium support so you are always ready for the next session. The mesh upper creates a breathable fit and meets up with a dual-density midsole to offer premium cushioning and stable comfort, while laser-siped flex grooves at the midsole create natural motion and a low-profile heel clip rolls up the sides to enhance traction.
