Removable inner sole shaped to foot imprint - is made from thick textile material which retains imprint under pressure

摘要

The inner sole is made in textile material, such as felt or fabric, which is at least 7.5 mm thick. It is sufficiently supple and maleable to deform and to mould to a shape that is impressed under a pressure of 1.2 kg/cm. The sole is cut to shape and it can be used as a removable inner sole. If the shoe has a moulded sole this is covered by a thin surface which only covers its edge and the inner sole covers the cells in the sole. USE/ADVANTAGE - The removable inner sole for the shoe retains the impression off the foot and makes walking less tiring.
