Sock Geek Says:

Note:  Size your recovery socks primarily by measuring the circumference of your calf at its widest point. Fine tune your fit by cross referencing that with your shoe size. If you don't know your calf size then order by your shoe size.

Post workout recovery sock with graduated compression engineering designed to promote increased circulation and lactate flushing in order to speed recovery.  Exceptionally supportive but very soft and comfortable.  Anti-microbial Lycra fabric is durable and holds its fit after numerous washings.  Ideal for wearing with your work clothes after a morning workout or during long distance air travel.
