For raw material uppers, such as: leather, leather, cloth, etc.,
and cut the specimen, the specimen is placed on a wet floor, under
a certain pressure to make repeated flexing action test. To detect
material resistant to penetration index, absorbent insole and
insole reconciliation adsorption capacity, or for the development
of improved materials, waterproof the basis
