ABSTRACT:
Apparatus and a method for testing leaks in the footwear articles are provided. Bootie and sock inserts for shoes made of waterproof materials in which the seams are seam-sealed have become popular among people who are involved in sports and other outdoor activities. Many of these products are sufficiently waterproof so that guarantees are made as to their waterproofness. A method for testing and apparatus for testing has been developed which can perform tests on multiple footwear articles simultaneously and produce immediate and reliable results within a matter of minutes. Footwear articles may include boootie inserts, socks, or shoes.
