Abstract
A device includes a foot-engaging element that can move in a spherical pattern and has resistance to movement generated by elastic straps. The straps can be added, changed or removed to customize the resistance to the exact pattern required to achieve maximum benefit for the user. The device does not require a user to place his or her weight on their foot to exercise, strengthen or rehabilitate an ankle. The device can be easily assembled and disassembled and transported.
