摘要： Devices and systems for providing dynamic foot support to a user are described. A device includes a heel support shelf, a foot support shelf, and a dampening device that allows relative motion of the heel support shelf with respect to the foot support shelf. When a wearer has on footwear that includes such a device, his or her foot is bent and flexed within the footwear during natural walking motion, thereby promoting blood flow, preventing stress, increasing comfort and reducing pain.
