The Nike Free Metcon 6 supports every workout. The athletic sneakers have forefoot flexibility and a reinforced heel with extra foam. The laser-siped outsole allows for better flexibility, and the big-toe side of the forefoot allows for better agility and quickness when making sudden movements. More foam has been added in the heel for improved stability. The foam in the forefoot and midsole offers comfort. The upper is made of breathable, supportive engineered mesh with stretch, and Flywire cables give a dynamic fit and keep you secure. These sneakers have a multi-surface traction pattern. The comfortable inner sleeve increases ankle support and provides a more seamless fit.
