The outer sole of my Sportiva approach shoes are coming unglued in several places. Any suggestions for a suitable glue for DIY repair, or do I have to throw them out after a year’s wear?
I've had good results with Gear Aid shoe glue. Clean the surfaces to be glued with white spirit, open the gap slightly and overfill with the glue, and then use tape to pull and hold the gap closed and leave for a day or so. It may not look very pretty, but it is quite effective.
