1000 Mile Walk Repreve Recycled Socks Twin Pack Perfect with all types of walking boot or shoe, the single layer 1000 Mile Walk Sock offers 3 season comfort and temperature control. This sock is designed to be a great all-rounder for those days spent adventuring. Built-in ventilation zones and the mix of fibres allow the foot to breathe and maintain an even temperature so you don't overheat or get chilly. The loop-stitched pile gives lots of volume and protection for plush softness and comfort. A padded heel and toe panels, a flat toe seam and arch bracing work together to help provide a customised fit with no slippage, reducing friction and so less chance of blisters.
