SmartWool PhD SocksSmartwool PhD Socks

For high-performing socks that can both be worn during activity, and to aid in recovery afterwards, we recommend the sport and sports-recovery PhD line by Smartwool. SmartWool's PhD socks offer the benefits of an active, performance sock whether you are spending your energy hitting the sloops or the pavement. SmartWool PhD socks use all-natural Merino Wool that is not only sustainable, but also offers superior moisture-management, minimizes odor, prevents blisters, and feels great on your foot. PhD socks take full advantage of Merino Wool's natural ability regulate temperature. Just as wool helps a sheep to stay cool in the summer and warm in the cold months, Smartwool socks respond to your core body temperature helping stabilize your temp--especially important during the long, hard workouts and the cool recovery time that follows. This regulation of body temperature goes so far as to even benefit your heart--afterall, the less your body needs to work at keeping you cool or warm, the more it can focus on other endeavors, like the long jump or catching the B17 bus.

Smartwool Graduated Compression PhD Socks

Smartwool PhD SocksSmartwool PhD Socks with Graduated compression technology apply varied pressure from the ankle to the knee, aiding in circulation and increasing blood flow back to the heart. So the legs don't swell and the body recovers faster. There are different levels of compression that are measured in millimeters (mm) of mercury (Hg), or mmHg. The higher the mmHg number, the more compression there is. Our SmartWool Graduated Compression socks combine the performance-enhancing benefits of Merino wool with the recovery-enhancing compression technology. SmartWool Graduated Compression PhD Socks are designed with recovery in mind. 20-30 mmHg compression rated, these socks are proven to improve blood flow, help move lactic acid from the lower legs to relieve muscle soreness, and reduce swelling overall. A solid choice for Bros who have a long flight ahead, work on their feet, train, or suffer from long-term leg and foot swelling. We recommend PhD Graduated Compression socks.
