Prosthetic sport feet

Abstract

Various features for improving the performance of prosthetic sport feet are provided. A fairing for a prosthetic sport foot can include foam components that are coupled to the foot and an elastane cover. The fairing is configured to alter the cross-sectional profile of the foot to produce a more aerodynamic shape. A prosthetic sport foot can include a hollow foot member that can be lighter weight and provide improved performance. A prosthetic sport foot can include an adjustable tension strap extending between and coupled to two portions of the foot member. A prosthetic sport foot, such as a prosthetic running foot or prosthetic cycling foot, can include an aerodynamic fairing and a cover. A prosthetic sport foot can have a varying-width profile such that a mid-section of the foot is narrower and a toe portion flares outward.
