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.
