Engineered mesh uppers will encase each foot in breathable comfort. Lightweight and highly breathable for all-temperature comfort, the mesh acts as a lightweight second skin, providing a supportive and comfortable fit. Its perforated construction allows air to fully permeate the entire upper, letting your feet breathe when the temperature starts to rise or your training session heats up. As well as radical ventilation, the double-layer construction delivers a premium fit that improves flexibility and decreases irritation-causing wrinkles (because we know how rubbing and blisters can ruin your day) while maintaining its lightweight. An exoskeletal heel counter, secures the rearfoot, helping to anchor you to the midsole and reduce in-shoe slippage so that you can enjoy smooth, distraction-free strides. A lacing system increases midfoot support to ensure a dynamic fit for all-day comfort.
