Waterproof breathable sole

Abstract

The present invention provides a waterproof breathable sole, comprising: an outsole provided with ventilation eyeholes in communication with the outer environment; and a waterproof breathable element comprising a waterproof breathable membrane covering the ventilation eyeholes; the waterproof breathable element further comprises a connecting ring; the connecting ring is provided around a periphery of the waterproof breathable membrane and engaged with the waterproof breathable membrane. The outsole may be further provided with an inserting groove; the inserting groove corresponds to a position of the ventilation eyeholes. The waterproof breathable element is received and sealed in the inserting groove; or the top of the outsole is flat, the waterproof breathable element is engaged with and sealed to the outsole via the connecting ring. The waterproof breathable sole further comprises a forced-suction and forced-discharge element correspondingly provided over the waterproof breathable element. The provision of the waterproof breathable element with the connecting ring simplifies the provision process of the prior art waterproof breathable membrane and improves the adaptability for the various type of soles; the provision of the forced-suction and forced-discharge element greatly improves the air circulation.
