This OS1st WP4™ Wellness Performance Socks features 50% more stretch for an extra-wide fit. Perfect for those who wear wide and extra-wide width shoes and want a comfortable sock. This sock has four zones of compression from light compression at the seamless toes and ankle for comfort to moderate compression at the arch for support and superior fit. The special contoured, nano-bamboo charcoal fibers create a cushioned footbed and heel areas to provide extra protection all while still being non-constricting. The sock uses micro-fiber nylon and OS1st’s signature silver-ion treatment creating anti-microbial and moisture-wicking properties for healthier feet.
