Men's Liner Sock Repreve M

"Use the 1000 Mile Ultimate Liner Sock as a blister-preventing base layer under thick walking socks for year-round protection, or as a standalone summer sock with lightweight boots. This double-layer sock features an inner layer that wicks away perspiration to the moisture-absorbing outer layer, keeping your feet dry. A blend of fibers, including the latest REPREVE® recycled yarns, along with top venting, maintains a comfortable foot temperature. Arch bracing provides extra support, while HeelPower fabric technology ensures a secure grip on the heel, preventing slippage." 66% Recycled Polyester 25% Nylon 8% Repreve Nylon 6 1% Elastine Medium - 6-8.5UK (EUR 39-42.5) Large - 9-11.1UK (EUR 43-46.5) XL - 12-14UK (EUR 47-49)
