The sole of my winter boot has cracked and come away from the boot a little. Its quite a clean crack and separation, so what's going to be best to stick it back on? Gorilla glue?
This stuff is cheap AND amazing!
Used it to stick the sole of my motorbike boots back on. Brilliant stuff.

Shoe Goo would do the trick. I had some Sikaflex adhesive leftover which worked on a pair of trainers: probably overkill though.
My Cedric Gracia North Wave enduro shoes have just done this. From the toe to just behind the cleat plate. Its currently on day 2 curing - apparently shoe goo doesn't develop full strength until 72 hours.
Update.
Shoe goo seems to have done the trick. Seems solidly bonded.
Shoegoo is good for self inflating camping mat repairs also!
