  • Insole for footwear
    Patent number: 4031586
    Abstract: This invention pertains to insoles and lasts for footwear. The insole has one or several protrusions which fit correspondingly disposed cavities in the outer sole thus assuring correct alignment of the outer sole and the insole at assembly. Lasting hooks are located around the insole which help to improve string-lasting and make possible a novel lasting method in conjunction with holes in the lasting margin of the upper. The last has two registration pins, one of them is firmly, the other one resiliently located in its bottom; they assure accurate positioning of the insole against the bottom of the last and eliminate the use of tacks.
