The most stable and durable METCON ever. Nike Metcon 6 is the most sophisticated Metcon ever. This means specific stability for weightlifting, traction made to ensure speed and strength where you need most. Textured print on the toe of the shoe increases durability ensuring lightness. The Coolest Metcon Nearly 18% more breathable than the Metcon 5, this version has lightweight mesh that keeps air flowing and your foot cool. A durable screen print reinforces the mesh without sacrificing breathability. Stability Under Weight A low, flat and wide heel creates a stable base for weighted exercises. A removable Hyperlift insert lets you adjust the height under your heel from one set to the next. Durable Traction Rubber tread on the outsole and up the side of the shoe provides traction on the ground and grip when you're climbing a rope. Focused Cushioning Foam is firmer under the heel for a secure feel and softer in the forefoot to cushion high-impact moves.
