What type of glue is best to repair/resole cross country ski boots with plastic soles?
Does anybody know a good type of suitable glue to repair a delaminated sole on (modern) cross country ski boots with plastic soles (Rottefella NNN in particular). The delaminated part is in the front with a bar for latching in a binding, so it has to withstand substantial forces. I am not 100% sure about the midsole (boot) material, but it's probably either soft plastic or gummi.
I am not sure if any common glue intended for trekking/walking shoe resoling will provide enough adhesion and/or will stick to plastic sole. Nevertheless, I was not successful when looking for information or advice targeting modern XC skiing boots in particular, so any hint is welcomed.
EDIT: I suspect the plastic is polypropylene (immune to acetone, and burn test on small chip, I cut away, suggests this too – though hard to tell from such little sample, so not 100% sure). This would rule out most of the common glue types on market, as these are usually not suitable for PP and PET, I am afraid

I have found that the best solution for my ski boots has been Gorilla Glue and Shoe Goo. Before applying you may want to score the area with a rubber file (like the ones found in bicycle repair kits), this will help the glue have something to hold onto.

I had the same issue with Karhu touring boots, delamination of the rubber sole front in the middle of nowhere, fixed for the return trip with velcro straps. I repaired this boot with barge contact cement, it has been tested on 3 outings. Of course the last trip the other boot started to unglue. Ran out of barge, now I am trying E6000, not tested yet. The E6000 dries with a better finish than the barge. I tested the E6000 on regular shoes, the one that I use in the garage for the dirty jobs and it has been doing well for over 6 weeks, but no cold weather in the garage.
