An article of footwear is provided in which the footbed is formed from a shoe last which is considerably thicker at the metatarsal region than conventional footwear permitting a much thicker insole to be received within the footbed. The thicker insole of a 3/8'' or greater throughout permits a range of different durometers of material to be used to ensure that maximum compression of the material is not reached through a stepping motion of a user of the footwear. A metatarsal insert and a combined heel and arch insert are received within respective cavities in a body of the insole so that durometers of the heel, arch and metatarsal region of the insole can be customized to a particular user's needs. The combined effect of the resulting thicker insole and varying durometers of the inserts therein results in a users applied weight being substantially evenly distributed across an entire footprint of the footwear during a stepping motion.

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.
