This puts you firmly in control of your fit, letting you adjust the amount of lockdown by tightening or loosening your laces. Co-molded midsole features a soft Phylon foam core inside a slightly firmer carrier for the perfect combination of lightweight comfort and durable protection. Tri-star outsole pattern allows the foot to naturally expand on impact while delivering lightweight cushioning and protection. Textured, solid rubber segments under the heel and toe for added durablity in high-wear areas.
