The OS1st BR4 Bunion Relief Sock is a first in its class! A one-of-a-kind sock that specializes in the treatment and prevention of Bunions and Bunion pain, medically known as Hallux Valgus. Treat yourself to relief and comfort with the OS1st BR4 Socks. The OS1st BR4 is specifically designed to relieve toe friction and bunion pain by separating the toes through our innovative split-toe feature. Our protective, supportive, and comfortable split-toe design makes this a go-to for relief and comfort during any activity. Unlike rigid bunion splints, braces, toe spacers, or bunion pads, our BR4 Bunion Relief Socks easily replaces your normal day-to-day socks and provide the relief you desire. A built-in “relief zone” features extra padding in a specially designed zone of comfort and prevents further damage by acting as a barrier, preventing blisters and continued rubbing from footwear which can lead to increased irritation of sensitive areas. Add to that, the BR4 is made with moisture-wicking, extra durable and soft micro-fiber nylon that provides extra cushioning without the bulk. Make the OS1st BR4 your first and last choice in Bunion Relief. This is a product made by foot care experts with the highest attention to excellence in manufacturing and product development. Hand wash and air dry for extended product life.
