The Nike Free Metcon 5 workout shoes feature forefoot flexibility with backend stability. A breathable, lightweight upper has a comfortable, sock-like feel with a 7/8-length inner sleeve and provides easy entry. Plush foam around the collar provides comfort and support around your ankle. The wide heel creates a solid base for lifting. A softer foam core cushions your foot, while a firmer outer layer is durable and stable. Wide internal webbing distributes pressure around your midfoot for a comfortable yet secure feel during sudden stops and quick cuts. Nike Free technology in the forefoot creates flexibility for agility moves like burpees, planks and sprints. Stretch around the collar lets your foot move naturally as you burst, cut and brake. The design incorporates a molded heel clip for support, webbing eyelets give you a snug, secure fit while also flexing with each step, and rubber tread in high-wear areas gives you durable traction. These athletic shoes are lace up.
