The footwear leak proofness tester  is used for determination of leakproofness.

Principle:

Seal the top edge of the test piece, e.g. with a rubber collar through which compressed air maybe fed via appropriate connections. Immerse the test piece in a water bath up to the edge and apply a constant internal pressure of 30±5Kpa. Oberve the test piece throughout the test and determine whether there is continued formation of air bubbles, indicating leakage of air.
