Abstract (en)
A shoe insole laminate includes at least one substrate film (11, 50, 60, 61, 70) having at least one layer of gas envelopes (10, 20, 30, 40) formed on the substrate film (11, 50, 60, 61, 70) at intervals and gas circulating passages (13) between the gas envelopes (12, 21, 31, 41). Each of the gas envelopes (12, 21, 31, 41) has a wall made of a pliable plastic material. The gas envelopes (12, 21, 31, 41) deform upon the application of pressure on the shoe insole laminate for shock-absorbing purposes. <IMAGE>
