Very Early Zipper (Apr, 1924)

GALOSHES FASTENED WITH KEY THAT LOCKS ROWS OF TEETH
Galoshes are being made to fasten with two rows of metal teeth that lock together as a “key” is pulled across them. It is claimed that this method permits the overshoe to be adjusted in a few seconds and leaves a smooth surface with no buttons or buckles. When the footgear is to be removed, a downward stroke of the fastener separates the two edges. Closing tighter than the ordinary galoshes, cold and moisture are said to have little chance to penetrate to the inside. The key is concealed under the folding top of the boot.
