Product Description High-performing and comfortable fastpitch softball socks! The construction is highlighted by a double welt top to stay in place, built-in arch and ankle compression zones for maximum support, and a cushioned sole that increases shock absorption on the heel and forefoot. A smooth toe seam also helps to provide blister control. This material is created with channels that wick moisture from your foot to the outer layer of the sock where it can evaporate more easily and the PolyPro material contains embedded antimicrobials to help resist foot odor.
