Our so-called “Light” polyurethane is the absolute best PU for straps that’s available on the market. Its main characteristics are: stability despite great lightness ( dime ), avoiding the classic problem that often occurs with expanded materials, high compression resistance (with tests already conducted in the laboratory) and an excellent surface without any defects, adaptable for every type of finishing, from the finest leather to thick cord, and finally, by using of course the right studs, the possibility of fixing the upper shoe to the polyurethane wall. And thanks to these characteristics, “Light” PU has differentiated Falpe in the market with respect to classic Pus.
