The OS1st FS4+ Compression Bracing Socks do it all! These socks are designed for active use and provide relief from ankle swelling, varicose veins, plantar fasciitis, Achilles tendonitis, heel and arch pain, and shin splints. With OS1st's Compression Zone Technology, these socks have five zones of medical-grade (20 - 30 mmHg) compression designed to stimulate blood flow and improve circulation, helping with active recovery in addition to pain relief. And, like any good performance sock, they are anti-microbial and made from moisture-wicking materials, helping to prevent blisters and keep your feet odor-free. The Y-gore heel pocket ensures your heel fits snugly into the sock, lining your foot up perfectly with the structure of the sock to make sure you take advantage of all the injury relief and prevention features the FS4+ Compression Bracing Socks have to offer!

Shipping FAQs

How long will it take for my order to arrive?

Most orders within the Continental U.S. arrive in 48 hours.

Sometimes certain products are not available in our stores so we are fortunate enough to be able to special order these items directly from the brands. Once an order is SHIPPED it should take between 3-5 business days for it to arrive at its destination.

Please note that these shipping timelines are only an estimate and that once an order leaves our stores, there may be carrier or customs delays that are outside our control. Additionally, we are not always able to make address changes after an order is placed, so please be sure your shipping address is correct before placing your order.
