Where reliable comfort meets tradition, you'll find our RBX Mid Socks. They're constructed from our ultra-lightweight, breathable, and moisture managing VaporRizeª yarns, which guarantee a soft, light, and airy interface between the foot and the shoe. Furthering comfort, we've included a four-inch double-welted comfort cuff that provides ample fit security without any pinching. And while you might not think of it firsthand, these socks also aid in performance. They feature a deep Y-heel and toe pocket to provide a secure, comfortable fit, plus a targeted textured zone under the forefoot that minimizes slip within the shoe to ensure maximum power transfer throughout your pedal stroke.
