The COURT sock was designed to provide maximum protection. The Double Layer design allows the two layers to move slightly to absorb friction. Both layers are constructed of Coolmax® for maximum wicking to keep feet cool and dry. The outer layer also consists of a fully cushioned foot for added comfort. A Stabilizer ZoneTM has been placed in the arch area for added stability and control. Finally, the heel and toe are reinforced with Twaron for added durability. All of these aspects make this the ideal sock for court sports. Fabric: Inner Layer 70% CoolMax®, 30% Nylon Outer Layer 77% CoolMax®, 17%Nylon, 3% Twaron, 3% Lycra® Color: White
