A granular rubber compound is melted into a liquid and then injected into a mould which produces a unit that incorporates the famous AirWair
technology, as well as offering resistance to a number of industrial elements, such as oil and acid petrol. The honeycomb design in the top portion of the sole
(below the midsole) creates shock-absorbing, cushioned air pockets. The sole
is then attached to the welt
by being placed against a red hot blade to create a watertight seal.
