The heart of any shoe is it's sole. In the case of Earth® it is our inclined Negative Heel® technology originated by Danish Yoga master Anne Kalsø to naturally align your body. Earth latex rubber or Dura-Light soles feature an exclusive rocker design to promote a natural walking motion. Every Earth foot-bed is fitted with Gelron2000®, a high tech EVA urethane compound that molds to the shape of your foot for a true custom fit that lasts for years. This is my 3rd pair of Earth shoes. It's really confortable and I adore their designs.
Earth Shoes are unbelievable. They're so comfortable, good for your posture and general well-being.
