A foxing is a strip of material, separate from the sole and upper, that secures the joint where the upper and sole meet, usually attached by a vulcanization process.
A foxing must be applied or molded at the sole and overlap the upper and substantially encircle the entire shoe.
Not only for vulcanized shoes, rubber-foxing tape is a must, but also EVA sandals and sport shoes are decorated with pre-vulcanized foxing tapes.
