Benefits of technology

[0005]The present invention provides bicycling shoes, having dual rigidity materials in the soles that are comfortable for walking while providing efficient energy transfer from the rider to the pedal when bicycling. The sole of the invention allows for more rigid or stiff materials in the pedal or cleat region of the shoe, proximate the metatarsal region of the rider's foot, thereb

Problems solved by technology

The flexible rubber sole, while flexible and cushioning for walking or running, unfortunately leads to inefficiencies and a loss of energy expended by the rider when energy from the rider's foot to the pedal, energy is lost in compression or flexing of the sole of the shoe between

Embodiment Construction

[0016]The present invention is drawn to an athletic shoe sole that provides enhanced comfort while walking and efficient energy transfer from foot to bicycle pedal when bicycling.

[0017]FIGS. 1 to 6 depict embodiments of the present invention. FIG. 1 shows a bicycling shoe 100 including an outersole 116, an upper 108, and a midsole 112 having at least two materials of different densities. The upper 108, may include a closure system 120, that can be any system capable of securing the shoe 100 to the riders' foot. The closure system may include shoelaces, a plurality of hook and loop (Velcro™) straps, zippers, and / or cords in conjunction with a dial to tighten the cords with even force across the throat of the shoe 100.

[0018]The upper 108 is attached to the midsole 112, which is attached to the outersole 116. As used throughout this specification, attachments may be made by conventional methods known in the art, such as stitching, welding and adhesive bonding. The upper 108 of the shoe...

Abstract

The invention provides bicycling shoes having soles containing materials of at least two different material densities configured to provide improved comfort, and fit for a wearer when walking or running in the shoes, while providing enhanced force transfer from the wearer to a bicycle pedal when bicycling in the shoes.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application Ser. No. 61 / 355,643 filed Jun. 17, 2010, which is incorporated herein by reference.TECHNICAL FIELD[0002]The invention relates to articles of footwear useful for touring or commuting by bicycle.BACKGROUND OF INVENTION[0003]When riding a bicycle, the largest force produced by the bicyclist is transmitted from the knee, through the foot to the bicycle pedal. A recreational bicyclist typically reproduces the pedaling force about 4,500 to about 7,500 times an hour. Unlike many bicycle shoes designed for road bicycle racing, mountain biking or commuter biking shoes typically have recessed cleats and a more flexible sole designed to allow the cyclist to comfortably walk or run when they dismount the bicycle. The flexible rubber sole, while flexible and cushioning for walking or running, unfortunately leads to inefficiencies and a loss of...
