Do you get blisters when you work out? Sweat can soften your skin, which will make you more prone to blisters when your foot rubs against your shoes. Then the friction can tear softer skin and cause blisters -- Ouch!
A sock that keeps your foot drier will help to prevent blisters from forming. Socks with wicking will help to wick (or draw) the moisture away from your foot to keep your tootsies dry and blister free.
I like: Patagonia's Lightweight Endurance Ankle Socks ($14.50) are lightweight and airy, with enough ankle coverage to stop the sock from slipping in the shoe. Buy them here.
Or you can try: Nike's AirMax 360 Dri-Fit Tab Sock ($7). Dri-FIT properties wick away moisture for rapid evaporation and cooler, drier wear and Air Max technology cushions feet against impact. Buy them here.
Fit's Tip: If you're blister prone then pre-treat problem areas. So say you always get blisters on your heels, pad them with moleskin prior to working out.
