The sole adhesive of my Vibram FiveFingers shoes had failed and I wanted to repair it with ShoeGoo. Some areas were easy to clamp for the 24H or so curing time but some of the does were going to be a challenge to get good surface contact. I designed these toes to fill the toe areas while the adhesive cured. I printed with ABS, 5 walls, 10% lightning infill. I may use my chamber vacuum to seal the shoes in a bag so the pressure of the vacuum presses evenly around the molds. If this is the case, drill or melt a hole in the toes so pressure equalizes.

I'm a size 12 so scale the toes to your needs. Sink them into the print bed in the slicer if you want them shorter.
