Castelli Free 6 Sock Men's

In the heat of summer, it can feel like your feet will never be cool again. In Castelli's Free 6 Socks, though, you might start to feel a little better about the sweltering dog days of summer. Castelli used Meryl Skinlife, an ultra light, ultra breathable fabric, which also happens to be antimicrobial. That adds up to cool, comfortable feet that don't stink. Not bad for August.
