Sock Geek Says:

Note:  Select your size primarily by measuring the circumference of your calf at its widest point. Fine tune your fit by cross referencing that with your shoe size.

Strategically positioned cushioned knee high compression sock that offers significant support to the Achilles tendon, tibia, calf, and ankle.  Padding is confined to the ball of the foot, heel and Achilles tendon while the rest of the foot receives supportive compression.  Left/Right anatomical fit for optimum fit.  Softer toe and heel area material for improved comfort.  SLS3 technology delivers approximately 34% more oxygen to the muscles thus reducing fatigue and increasing endurance.  Anti-microbial properties in the fabric eliminate unnecessary foot odor keeping you fresh. 50 SPF for added protection for those long hours spent in the sun.  Worn regularly SLS3 Compression Sox will reduce post run soreness and increase recovery time.  Compression 20-30mmHg.

Note:  SLS3 uses polypropylene because it absorbs 300% less moisture than traditional nylon.
