Abstract: A shoe sole having improved cushioning characteristics is disclosed. The sole includes a midsole having a top layer of material and a bottom layer of material. In one embodiment, the top layer of material may be harder than the bottom layer of material. A pattern of lugs defining a wave may be formed on the bottom layer of material. The wave may generally be in the shape of sine wave so as to provide improved cushioning characteristics for the sole. An outsole may also be formed on the bottom layer of material and an upper may be connected to the top layer of material, such that a shoe is formed.

Abstract: A suspension heel is provided for use with footwear, such as high heeled shoes, to provide cushioning to the wearer. The suspension heel includes a heel shaft connected to the shoe sole and a compliant heel plug attached to the heel shaft. The shaft includes a cavity or other receptacle for receiving the compliant heel plug. The suspension heel provides cushioning as well as stability for the wearer of the footwear, while maintaining aesthetic style. A relief detail formed by the compliant heel plug and the shaft provides compliance by compressing when a force is applied. For instance, as a person walks in the shoe, ground contact applies a force to the suspension heel. The relief detail deforms or compresses in response to the force, attenuating it and providing cushioning to the wearer.

Abstract: A residue clearing apparatus for a shank of an agricultural implement includes a spoked wheel adapted for attachment to the implement such that the spoked wheel rotates about a wheel axis oriented substantially horizontal and perpendicular to an operating travel direction of the implement and forward of the shank. A drive is operative to rotate the spoked wheel. The spoked wheel is oriented such that ends of spokes of the spoked wheel pass above the ground forward of the shank, and such that the ends of the spokes of the spoked wheel pass adjacent to a front face of the shank. The spokes may be resiliently or pivotally mounted to the wheel.

Abstract: An implement apparatus includes a hitch frame, center frame section, and right and left wing sections pivotally attached to the center section. An actuator pivots the center frame section upward about the hitch frame axis at the rear of the hitch frame to raise the frame sections upward and rearward from a horizontal aligned operating position, where front ends of the frame sections are forward of the hitch frame axis, to a raised position where the frame sections are oriented vertically. Working members mounted to the frame sections forward of the hitch frame support the apparatus on the ground in the operating position, move upward off the ground in the raised position. Transport wheels rearward of the hitch frame axis are above the ground in the operating position, and move down to support the apparatus in the raised position, where wing sections can pivot rearward to the transport position.

The spoked wheel is oriented such that ends of spokes of the spoked wheel are above the ground forward of the shank, and such that the ends of the spokes of the spoked wheel are located adjacent to a front face of the shank. A drive is operative to rotate the spoked wheel.

Abstract: The present invention provides articles of footwear adapted for use in extreme and hazardous environments by members of the military, law enforcement personnel and others who require durable and functional footwear. The footwear include protective coverings that may be proof, puncture proof, fire retardant or water repelling. Drainage holes can be positioned in the toe region and along the outsole to enable a wearer to quickly drain water from the article of footwear. Single use or replaceable drainage plugs may cover the holes to prevent entry of water into the boot or other article of footwear. Removable and/or replaceable footbeds may be employed, and such footbeds may provide adjustable sizing of the article of footwear using interchangeable cartridges. A support saddle may be employed with the footbed to enhance foot support under heavy loads. These and other features herein are suited for use in a wide variety of footwear.

Abstract: The present invention provides an interchangeable shoe footbed cartridge system. The system includes a footbed such as a midsole, insole or a sockliner. A cartridge is inserted into or otherwise attached to the forefoot section of the footbed. Multiple cartridges of varying depths, widths and/or lengths may be provided. The wearer can select a cartridge to achieve a desired fit. Because right and left feet may be of different sizes, different cartridges may be chosen for each foot. Furthermore, the user may swap cartridges depending upon different conditions, or to change the stiffness of the cartridge. Additionally, a slipcover having a stretchable portion may be placed over the cartridge system. The cartridges enable a footwear manufacturer to produce fewer shoe sizes while fitting more of the population. This reduces manufacturing, shipping, warehousing and accounting costs. All levels of the supply chain, as well as the end customers, will greatly benefit from the method of supplying footwear.

Abstract: An article of footwear having an upper and a sole is disclosed. The sole of the article of footwear includes a midsole having a support portion and a plurality of projections extending from the support portion. The sole of the article of footwear also includes a plate contacting the support portion having a body positioned in an area between the plurality of projections. The plate further includes a plurality of openings which correspond to the plurality of projections and allow the projections to extend below the body of the plate. The plate further includes a plurality of cantilever elements extending on at least one side and on the bottom of each of the plurality of projections. The projections and the corresponding cantilever elements interact with one another to form a plurality of lugs located on the sole of the article of footwear.

Abstract: The present invention relates to removable and/or replaceable liners for use in a wide variety of footwear. Liners may be permanently connected to the collar of the shoe, or may be semi-permanently attached for easy removal from the collar. The liners can be quickly removed from the interior of the shoe using any number of disengagement devices. Removing the liner from within the shoe permits rapid drying of the liner when it becomes wet due to moisture generated by the foot within the shoe or from external environmental conditions. Semi-permanently attached liners can be detached for cleaning or for replacement by another liner depending on the needs of the wearer. Disengagement means can be provided in conjunction with the liner, which enable the wearer to easily pull the liner out of the shoe.
