502, 10 1 etc. Definitely can't be used (these are all cyanoacrylic adhesives, not hard adhesives and materials); However, the brothers and sisters belong to AB glue (a modified acrylic glue, which is hard glue and afraid of water), and they still can't be used.
To stick shoes, of course, you should use the glue (polyurethane) from the shoe factory. This kind of glue can't be bought in stores, so you can only get it from shoe glue suppliers or shoe factories.
In the past, our factory used green leopard resin glue, which should not be found in the market. It should be sold online now. If you are looking for a treasure, this is the name you are looking for. Come back when you find it. Thank me.
Don't buy light yellow ones, which are chloroprene rubber (commonly known as "yellow rubber" and "all-purpose rubber"), and need vulcanizing agent (falsely called "reinforcing agent"), which will make shoes brittle after 4 days. Don't buy this!
