<p>The shoe has an air-cushioned sole or several soles, with an upper, heel and valve. The shoe which can be in the form of a sandal or boot presses several air compartments which are inflated with the mouth or with a pumo and filled with gaseous material. Alternatively, the soles can incorporate springs or spirals to produce the cushioning effect. Between the sole facing the foot, and the shoe sole there can be several pressurised compartments which are regulated in pressure by a pressure valve. The colour and material forming the shor can be of any form. Any leaks in the air compartments can be required by spraying sealant.</p> |
