These running socks that we manufacture in Sweden come in white with a navy stripe and another stripe in either burgundy, mustard yellow or dark green. The upper has a thinner mesh knit for maximum moisture transport and comfort. The terry stitch in the heel, toe and under the tread pad protects the foot and has a shock-absorbing function. Hollow foot support on the middle of the foot keeps the sock in place. Minimal toe seam. Above the heel, we have made a rise to avoid shoe chafing and the sock falling down.
