Men's Running Socks
Smartwool men’s PhD® Run socks are designed for maximum comfort and performance, with sock heights and cushioning options for all types of runners. Our Ultra Light (non-cushioned) option is for those who like the bare minimum feel between their feet and shoes, while the Light Elite features targeted cushioning on the heel and ball of the foot for maximum impact protection.

Men's Running Socks
Our PhD® Run sock collection features our 4 Degree™ elite fit system for a performance fit (no more blisters!), Indestructawool™ Technology for durability, and a Virtually Seamless™ toe for enhanced in-shoe comfort. And because they’re made using Merino fibre, they’re naturally breathable, moisture-wicking and stink-free, so they’re always ready to head out the door when you are!
