Performance is vital when every play counts. We've created a baseball sock that not only looks great but exceeds everything else on the market when it comes to durability, technology, and design. The Diamond Pro OTC has a built in cushion at the ankle which provides additional padding and protection against grounders. A custom blend of fusion fibers maximizes durability throughout the entire design while a mosaic of seamless mesh panels further enhances breathability and thermoregulation. For unrivaled comfort and support, the sock applies targeted lateral compression and seamless toe closures. You won't find a better baseball sock than the Diamond Pro OTC, the official sock of MLB.
