Description from Hike Footwear website: Stiff soles and immobile shoes can cause painful symptoms in your nervous system and do not support your natural anatomy during daily activities. The most natural way to walk is barefoot. The ultra-light and flexible 4mm thin sole allows a natural gait, promoting the natural alignment of your feet. This effectively prevents common discomforts in your knees, hips, back, ankles, and feet. With Hike-Lorax barefoot shoes, you\'re choosing comfort, healthy feet, and a natural walking experience. These unique shoes give you the feeling of walking barefoot while providing protection and support. Our barefoot shoes are specially designed to give your feet room to breathe and move, just as nature intended. Not only do they enhance the strength and flexibility of your arches, but they also align your body for natural stability and balance.
