Hilly Active Women's Socklet (Twin Pack) The Hilly Active Socklet are ultra-light, soft and comfortable making them perfect for an active lifestyle. The Active Quarter Socks provide you with minimum level cushioning in areas you need it the most.

The socks feature a vented upper, which works by allowing air to fully permeate the fabric construction and provide a constant supply of fresh, cool air. Alongside this, the warm air will be pushed out, providing a perfect microclimate for your feet, so you can enjoy every stride.

A flat under toe seam construction also ensures a smooth non-abrasive experience when wearing the socks in intense circumstances, and tabs at the front
