Maybe you're training for a marathon. Or you're pulling a double shift that keeps you endlessly on your feet. Either way, Smartwool PhD® Running Low Cut Socks deliver an "advanced degree" of support, cushioning and breathability. SmartWool's exclusive 4-Degree™ Elite Fit System means they fit like a second skin – no slipping, bunching or chafing. Soft, naturally wicking Merino wool helps regulate temperature, fend off odor and prevent blisters. Plus a helping of nylon adds strength, and elastane adds supportive stretch. Light, half-cushioned footbed softens every footfall. Isn't it time to graduate to a higher-performing sock?
