Abstract: A vulc style and cupsole style footwear and a method for manufacturing the footwear are disclosed. The footwear includes a midsole that is directly attached to the upper. The midsole may be attached to the outsole by adhesive. In the method of manufacturing the footwear, the upper and an outsole are disposed a set distance apart. Polyurethane or other material for providing cushioning to the footwear is either injected between the upper and outsole or poured onto the outsole and the upper is traversed over the outsole so as to define the mold for defining the midsole. The polyurethane is directly attached to the upper and adhered to the outsole/cupsole.

Abstract: A sole of a footwear is provided herein which may be designed to provide multifunctions suitable for particular sports. The sole may include a bladder which extends an entire length of a wearer's foot. The bladder may be pressurized with fluid for absorbing impact forces (e.g., landing impact forces, running impact forces, etc.). To prevent the bladder from having a balloon configuration, support columns may be attached to an upper layer and a lower layer of the bladder to maintain the spacing between the upper and lower layers. The lower layer of the bladder may be flat for optimizing the sole for skateboarding and other activity.

Abstract: This invention discloses an interchangeable midsole for use in the manufacture of shoes. The embodiments of the invention allow for greater rigidity, durability, and comfort for shoes to be used in every day life and in extreme sports as well as impact and abrasion protection for the wearer's feet, no matter what the wearer is doing. One or more embodiments of the invention are adapted to provide skateboard riders with increased durability and comfort in their riding shoes. Furthermore, because the novel midsole design is interchangeable among various shoe soles and uppers, the manufacturer is able to adapt various shoe designs and configurations around the common midsole.
