The dominant ankle sprain is an inversion injury, where your ankle rolls toward the sole of the foot, causing pain. If you experience this injury, wear an ankle support that has metal or plastic supports on the outside of the ankle. This supports the injured ligaments on the ankle’s outside. Eversion sprains are less common, but occur when the foot rolls outward, resulting in a sprain. This injury type requires an ankle brace that features support on the inside as well as outside.
