COPPER INFUSED COMPREHENSIVE PROTECTION -- Made from 85% nylon, 10% spandex, and 5% copper yarn. The copper ions in the yarn not only absorb sweat and keep your legs dry and odor-free but also warm your calf muscles and promote blood circulation, helping to relieve muscle soreness and shin splints. PROFESSIONAL GRADUATED COMPRESSION -- Designed with advanced compression technology. Kodal calf sleeves feature 15-22 mmHg graduated compression to meet the pressure needs of different leg areas, increasing your legs' metabolic rate. INJURY PROTECTION & PAIN RELIEF -- Engineered with an ergonomically curved line. Kodal compression sleeves for shins provide complete protection for your calves against injuries during exercise or daily gym activities. Simultaneously, these calf sleeves work effectively for recovery from varicose veins, shin splints, or sports injuries. SUPER ELASTIC & BREATHABLE -- Available in FIVE sizes for your selection. The highly elastic, snug, and breathable compression material fits tightly against your calves while keeping them dry, itch-free, and odor-free. The high-quality fabric is also washable, ensuring long-lasting use!
