The Tactel Ladies Trainer Liner Socklet utilises the unique 1000 Mile double layer system with a Tactel inner liner for optimum racing performance and comfort. The inner layer stays with the foot and the outer layer moves with the shoe, preventing blisters and wear through a reduction in friction. The combination of fibres and ventilation allow for unmatched comfort through temperature regulation whilst arch bracing provides additional support.*Outer layer consists of 76% Cotton, 22% Nylon and 2% Lycra.*Inner layer is constructed from 100% Tactel.
