The solution? A lightweight, pull-on design that combines the flexibility of socks with a grippy, structured, shoe-like sole. Peter packed many other feet-pleasing features into his washable barefoot sock shoes. The stretchy knit upper is made with moisture-wicking, silver-infused, antibacterial yarn. This keeps odors at bay and feet feeling comfortable. At the bottom, a structured sole made with Swedish polymers offers grip and stability, whether you're at the gym, on a hike, or traveling. Skinners are washable and portable, so a pair can go pretty much wherever you want to—just roll them up and head out.
