Patent abstract
A footwear system has a sole unit with a number of cavities formed between a midsole and an outsole. The cavities are complementary to one another to form groundward oriented air bulges in the outsole that are connected by a passage formed in the midsole. The passage permits movement of air between the cavities during use of the footwear system in a shoe.
