OS1st FS4+ Over the Calf Pickleball Compression Socks

The OS1st FS4+ OTC Socks are the perfect choice for both performance wear and recovery so you don't have to choose between comfort and functionality. This proprietary design is made with FS6 technology which reduces swelling and symptoms of plantar fasciitis, along with general foot and leg pain. Compression Zone Technology specifically targets areas of frequent strain so you'll enjoy enhanced support and fewer days of rest and recovery.

OS1st FS4+ Over the Calf Socks use a compression strength of 20-30mmHg which is considered medical grade. They can help minimize varicose veins, Achilles tendonitis, arch pain, and shin splints while mitigating overuse injuries in the future. The material is a gentle micro-fiber nylon which not only feels pleasant, but wicks away moisture and lasts over time.

The FS4+ OTC Pickleball Compression Socks from OS1st are not simply footwear, but a targeted rehabilitation tool which you can wear with ease every day.
