MOISTURE WICKING: We are using a fabric to wick sweat away and help keep YOU dry and comfortable. The lightweight mesh vents of these marathon running socks offer excellent breathability for more comfort. SIZING INFORMATION ON THE LEFT – PICTURES. BLISTER TAB: Blister tabs are reinforced cushions built into SLS3′ heels that prevent chafing and blisters from shoe contact. HAND-LINKED TOES: Our hand-linked toe seam eliminates the annoying bump that runs across the toes of most cushioned running socks. You won’t feel a thing. This is a highly skilled process, every stitch is carefully linked (toe closed) together by eye/hand to create a completely flat seam which is great for comfort. ADVANCED PADDING TECHNOLOGY: The athletic running socks feature light cushioning in key areas including the heel, Achilles and toes, thanks to the padding that is located in key areas of the sock. This special padding offers YOU shock/impact absorption and added comfort. VALUE: Thanks to our consumer direct business model we are cutting out the middle man and offering these 3-packs of workout socks at a cost that our competitors charge for one pair. This means you get three times the value with better performance socks at a much lower price.
