 Some modern shoe manufacturers have recently designed footwear to mimic the barefoot running experience, maintaining optimum flexibility and natural walking while also providing some degree of protection.The purpose of these "minimalist shoes" is to allow one's feet and legs to feel more subtly the ground, allowing more accurate adjustments in running style.Most minimalist running shoes are based within a scale from 1–10, where 1 is barefoot and 10 is a typical athletic shoe sole.
