SmartWool PhD Graduated Compression Light Socks feature dense cushion pads under the forefoot and heel for protection and comfort, while merino wool naturally helps manage moisture, temperature and odor on-the-run. Graduated compression of 20-30 mmHg stimulates blood circulation to decrease muscle recovery time, and Smartwool's updated fit with enhanced stretch feels comfortable every time you slip them on.

Customer feedback

Comments: Amazing socks. They do not lose their compression after multiple uses. I feel like they have a good amount of compression, but not too much, so that you can wear them all day.
