Abstract
Methods of using a foot device are disclosed herein. The foot device includes a generally U-shaped portion having an arcuate portion and first and second legs extending from the arcuate portion. Each leg has an end and a relief area disposed adjacent the respective end. A method of using the foot device comprises engaging the arcuate portion with a heel of a foot to form a first point of contact; positioning the relief area of the first leg proximate a fifth metatarsal head of the foot such that the fifth metatarsal head drops to form a second point of contact; and positioning the relief area of the second leg proximate a first metatarsal head of the foot such that the first metatarsal head drops to form a third point of contact, wherein the first, second, and third points of contact form a triangle-shaped contact surface.
Claims13
A method of using a foot device, the foot device configured to receive a foot of a user, the foot device including a generally U-shaped portion having an arcuate portion, a first leg and a second leg, the first leg and the second leg extending from the arcuate portion, each leg having an end and a relief area disposed adjacent the respective end, each relief area angled back from an inner edge of the U-shaped portion toward an outer wall of the U-shaped portion such that the part of the relief area furthest from the arcuate portion is at the inner edge and the part of the relief area closest to the arcuate portion is at the outer wall, the method comprising:
- engaging the arcuate portion with a heel of the foot to form a first point of contact;
- engaging the first leg of the arcuate portion with a lateral portion of the foot such that the weight of the foot is transferred from the first point of contact along the first leg of the arcuate portion;
- disposing the relief area of the first leg proximate a fifth metatarsal head of the foot such that the fifth metatarsal head drops to form a second point of contact;
- engaging a base portion of the foot device with fourth, third, and second metatarsals such that the weight of the foot is transferred medially from the second point of contact along the base portion of the foot device;
- and
- disposing the relief area of the second leg proximate a first metatarsal head of the foot such that the first metatarsal head drops to form a third point of contact.
A method of using a foot device, the foot device configured to receive a foot of a user, the foot device including a generally U-shaped portion having an arcuate portion, a first leg, and a second leg, the first leg and the second leg extending from the arcuate portion, each leg having an end and a relief area disposed adjacent the respective end, each relief area angled back from an inner edge of the U-shaped portion toward an outer wall of the U-shaped portion such that the part of the relief area furthest from the arcuate portion is at the inner edge and the part of the relief area closest to the arcuate portion is at the outer wall, the method comprising:
- engaging the arcuate portion with a heel of the foot to form a first point of contact;
- positioning the relief area of the first leg proximate a fifth metatarsal head of the foot such that the fifth metatarsal head drops to form a second point of contact;
- and
- positioning the relief area of the second leg proximate a first metatarsal head of the foot such that the first metatarsal head drops to form a third point of contact, wherein the first, second, and third points of contact form a triangle-shaped contact surface.
