The Sparthos Calf Compression Sleeves are designed to provide you with the perfect amount of calf support without limiting your ability to move, train, and play. The aim of our compression sleeves is to aid in the recovery process. Your muscles and joints need oxygen to repair themselves but it typically takes much longer for oxygenation to reach your joints. This means your legs, calves won't feel swollen, sore, or tender as normal when you wear a pair of sleeves. The sleeve absorbs shock waves that occur as a result of intense sports like running, hiking, cycling, weightlifting, and so on. If you plan on staying physically active in these sleeves, you dont have to worry about them generating a ton of sweat. The fabric allows moisture to evaporate from your skin quickly. Built For Performance & Comfort Boosts Your Performance Less pain, better circulation, and healthier legs mean better outcomes in everything you do. ?
