Layers of cushioning, in some athletic socks, are knit in to reduce impact. Mapped socks are activity-specific and will offer cushioning in common pressure areas.


Choose socks that fit the footwear you'll be using and the activity you’ll be doing. Thickness is not comparable across all type of socks. For example, thin ski socks may be heavier than thin cycling socks.

Anatomical Fit

Left foot and right foot specific socks provide precise fit.
