Hello all, I want to repair my Scarpa "approach" shoes. They're called "approach shoes" as they are intended to be used for light rock climbing and/or hiking to get to the wall that one plans to climb, but, I don't use them for this purpose. The soft, rubber climbing sole wore out after only 6 months of biking and longboarding, so I had them replaced with Vibram soles about 2 years ago. In short, after washing and leaving them in the sun to dry, the rubber toe-cap has come unstuck in several places and the Vibrams as well. (see pics)
Several shoe repair shops gave me quotes too high for my budget, but provided me with a good idea of how to proceed. They all said that the toe-cap needs to be reglued AND sewn down, otherwise it will just come unstuck again. Of course the sole also needs to be reglued.
What I want to know is: A) What type of glue and technique can should I use to reglue the toe-cap and sole? and B) What type of needle, thread and stitch should I use to sew the toe-cap?
