I have a pair of leather ballet flats that are lined on the inside with cloth glued down to the leather insole. The problem that I have is that the cloth comes up when I'm not wearing nylons with them. The whole front of the foot part comes up and makes them very uncomfortable to wear. Is there a glue that I can use that will be durable and keep the damn insoles down? Do I need to take them to a shoe repair place? If it's something I can do myself I'd prefer to, funds are tight on a college student's budget, but I want to know the best way to fix them. Thanks!
