Shu-Lok Shoes, Part 3:
The Talon Shu-Lok fastener was used by several different shoe manufacturers, including Thom McAn, in the late 1950’s and early 1960’s. They came to be knows as “Snap Jacks,” “Mousetraps,” or “Grasshoppers,” and were apparently prized in Rockabilly circles because musicians like Carl Perkins were photographed wearing them.
And that’s all I’ve been able to find out. If you know anything else about them, drop me a line.
