ENERGIZE YOUR LEGS Using integrally-knit graduated compression, our compression socks apply therapeutic pressure that starts at the ankle and gradually eases above. Its this external pressure that energizes your legs and REDUCES SWELLING. ALLEVIATE ACHINESS & HEAVINESS By squeezing the legs from the bottom up, our legwear can help INCREASE CIRCULATION of freshly oxygenated blood back to your legs. MEDICAL GRADE CLASS II 30-40 mmHg should only be worn when prescribed by your doctor.
