Vintage HEWETSON CANADA Leather Bowling Shoes

Delightful vintage HEWETSON CANADA dark red bowling shoes complete with carrying case! I would say these have not seen a lot of use. Minor scuffing. There is a small hole at the back of each shoe, as if a stick pin had been there. I’m guessing there might be a bowling tradition whereby something is put on the back of the shoes, but I don’t know for sure (see pic). The stamped size info inside the shoes is a bit hard to read. I’m assuming these are 6.5. I’d love to hear other opinions on this! rockabilly Grease flats fun
