Zero-drop shoes provide the best foundation for a natural and upright posture. When we wear shoes that drop from the heel to the toe, it disrupts the alignment of our entire body. Wearing high-heeled shoes can chronically shorten your calf muscles and reduce the range of motion in your ankles, leading to pain in your Achilles tendon. To save you from all these problems and provide you with benefits, we don't use heels in our shoes.
