The McDavid Sport Knee Patella Support Strap helps relieve pain associated with Runner's Knee and Jumper' Knee. It provides light support in a stable, comfortable and breathable strap design that's easy to wear all day for almost any activity — whether you're working out or staying on your feet. A tubular, non-slip buttress applies constant uniform compression at the patellar tendon, helping deliver relief with support and stability. The strap is easy to use and fit correctly thanks to an adjustable hook and loop closure that allows for an easily customizable fit no matter who is wearing it. Spandex (elastane) binding promotes comfort in a durable construction for high-quality performance and long-lasting wear. The McDavid Sport Knee Patella Support Strap fits either the left or right knee.
