These attractive socks are joined together stitch by stitch resulting in no ridges and a no irritation flat knit toe seam. A better fitting, softer and more comfortable sock means no abrasions or blisters. The elastic at the top of most socks is insufficient to keep them in place, so these technical socks have additional Lycra support sections throughout the calf, so you won’t find them cutting off circulation or falling down in to your boot. Lightweight polypropylene from Schoeller offers excellent wicking and fast drying. The Boot socks, made of 75% Schoeller Polyropylene, 15% Nylon and 10 Lyrca, are longer to provide additional warmth and support to the lower leg. Built for miles and miles of use. M (5.5-9.5), L (10-12.5), XL (13-15).
