Cycling Socks


PhD® cycling socks are developed for the long ride. We wanted to create cycling socks that fit so well, you forget you’re wearing them, even after a full day on the saddle. So that’s what we did. Whether your biking legs prefer tacky single track or long ribbons of road, the longer a ride lasts, the more important comfort becomes.

The 4 Degree™ elite fit system makes sure your bike socks don’t bunch or slip in your shoe which helps prevent blisters and irritation. Soft, ultra-fine Merino wool helps move sweat away from your foot, resists odors and helps keep feet comfortable even when that foot-drenching puddle comes out of nowhere. And when you hang your helmet up for the day, the easy care benefits of Merino mean those cycling socks are washer and dryer friendly.  Ride on, because we’ve got comfort covered.
