Waterproof shoes are generally sealed with a membrane which can be conceived as a type of inner shoe inside the upper. To seal the seams, we use a seam sealing tape which is welded to the membrane using hot air

Mesh tapes are ideal for achieving a waterproof connection between the injected sole and the membrane. The PU foam of the sole penetrates the open mesh tape fabric, thereby creating a waterproof anchor for the membrane in the sole.
