Soft engineered mesh has 3 advantages to help your next run: Lightweight so you can feel fast. Structured fit for stability. And breathability for airflow so your feet stay cool. Made right for kids' feet and for running, our Cushlon foam gives a responsive and bouncy feel with every stride. A Zoom Air unit in the forefoot brings a quick off-the-ground sensation. The rubber sole has a waffle-inspired traction pattern to help grip surfaces and provide durability. The cutout grooves increase flexibility for a better transition from heel to toe. A synthetic leather midfoot band stretches across the top to give you a secure and stable feel while running and moving in different directions. Extra skin layer across the toe tip provides added durability for those who drag their toes. Padded foam collar gives extra comfort and support around the ankle.
