Not too high, not too low, just right in the Core Run Mid 2P Sock
What Our Gearhead® Experts Are Saying:
"I reach for these on longer weekend runs when I want a bit more coverage without going full crew height. The rib cuff keeps them from slipping down even after an hour plus on the road."
Some runs call for a little extra coverage without going all the way up the calf, and the Core Run Mid 2P Sock hits that middle ground perfectly. Lace up for a long weekend run or an easy recovery jog, and let the seam-free fit and rib cuff keep everything locked in place as the distance adds up. Terry cushioning underfoot softens every footstrike, while side ventilation panels keep feet from overheating no matter how far the route wanders.
