SmartWool socks have always been smarter than the rest.
Now they have a doctorate in performance and comfort.
Smartwool introduces the PhD line--socks designed for maximum sport-specific performance and drawing on their own in-depth
physiological research, with styles tuned to runners' and
cyclists' unique needs. As if that's not enough, they revamped the
SmartFit System for an even better, sport-specific fit. Some say
PhD is the smartest sock in the world. We say they're a prescription
for serious performance and comfort.
