The infused medicine in our calf & shin compression sleeve is contact-activated to release safely into your skin for targeted pain relief. The compressive fabric works in tandem with the built-in medicine, reducing pain, swelling, and soreness while simultaneously supporting your vascular system to improve circulation. Excellent for soothing calf cramps and shin splints, the long-lasting embedded medicine is effective for as long as you wear the sleeve and lasts for over 15 washes. View full details
