Abstract
A shoe cleat with improved traction includes at least one resiliently flexible traction element extending from a hub and being resiliently deflectable in a direction toward the sole of a shoe when the cleat is secured to the sole. The cleat is further configured to trap and engage blades of grass during resilient deflection of the traction element when the shoe is forced against a turf surface. The grass blades are frictionally engaged and secured in a non-planar engaging area by the traction element resulting in an enhanced traction of the shoe with respect to the turf surface. A convex foot on the traction element includes a suitable curvature to facilitate sliding of the foot along the turf surface as the traction element deflects to avoid penetration into the turf.
