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.
