OS1st TS5 Travel Socks were designed with the active traveler in mind.

Made with ultra-soft yet durable microfiber, they are designed not to bind, bunch, or pinch. Performance features include a seamless, left/right toe design; moisture wicking and odor control properties; blister protection; and support for the overall foot structure.
