ABSTRACT:
There is provided a shoemaking material which comprises a laminate of two webs having different apparent densities. One web has an apparent density lower than 0.4 g/cm.sup.3, and the other web has an apparent density higher than 0.3 g/cm.sup.3, with their difference being greater than 0.1 g/cm.sup.3, preferably greater than 0.3 g/cm.sup.3. The laminate has a weight of 200 to 1500 g/m.sup.2. The shoemaking material of such structure has a soft face layer which provides cushioning properties and a hard core layer which keeps the shape of a shoe. Because of this unique structure, it permits moisture to pass through and dry rapidly. Thus it keeps shoes in good sanitary condition and makes shoes more functional.
