As seen on Shark Tank! Addictively comfortable shoes and sandals for everything you do. Xero Shoes are all about NATURAL -- Imagine taking off your shoes at the end of the day. If you'd be more comfortable once you do that, then you've been wearing the wrong shoes. Your feet are made to bend, flex, move and FEEL the world. One-quarter of the bones and joints in your ENTIRE body are in your feet and ankles; you have more nerve endings in your soles than anywhere but your finger tips and lips. Comfort and performance come from using your feet naturally. That's what Xero Shoes let you do. - Natural Fit -- wide toe boxes let your toes spread and relax. A non-elevated (zero-drop) heel for proper posture. - Natural Motion -- super flexible to let your feet bend and move naturally. Low-to-the-ground for balance and agility. - Natural Feel -- the patented FeelTrue® soles give you just-right protection while still giving the ground feedback your brain needs for efficient, natural movement. Plus the soles are backed with a 5,000 mile warranty.
