ACCIDENT PREVENTION INSOLE

摘要

An accident prevention insole includes a base surface (2) and a top surface (3) opposite to the base surface (2). The accident prevention insole (1) consists of a multilayer fabric (4) which can be crossed-through from the base surface (2) to the top surface (3) and vice versa by needles with a diameter lower than 14 tenths of millimetres perpendicularly driven to the insole with a load of at least 90 N, for directly sewing the insole to an upper (101) of a footwear (100), preferably with a Strobel technique.
