The more supportive the shoe, the more stability it can give to your natural stride. A combination of tuned support and intentionally placed cushioning helps you feel secure with every step. The Peg 40 has neutral support. It gives you balance, whether you're a heel or forefoot striker. It's good for long and short runs, too, providing a smooth transition from heel to toe. The more cushioning that you have underfoot, the softer and more comfortable your running experience can be. Cushioning helps soften impact as your feet hit the ground. Feel connected to the ground with Nike React technology, a lightweight, durable foam that delivers a comfortable, responsive ride. It holds its shape run after run to give you a consistent feeling. The more responsive the shoe, the more energy return you can get back with each step. Whether you want to run a little bit faster or with a little less effort, responsive shoes help give you slightly more spring in your step to get more out of your run. A highly tuned single layer mesh creates an inviting feel and fit. Suede material allows it to provide better fit without irritation, from your 1st run to last run. Heel area optimizes the landing space and improves transition and durability. Waffle-inspired pattern provides traction for the road. Extra flex groove offers a smooth toe-off.
