Most likely it's ABS plastics. Why is says not to use the glue on polyethylene
or polypropylene is because it doesn't stick to them.
Glues that stick to those plastics are expensive and only recently invented.
With Gorilla glue and other moisture activated polyurethane glues, you must use
clamps or weight to hold the things being glued so that they cannot move. The
glue foams and expands as it cures. That will push the pieces out of position.
The glue can also ooze out and get onto surfaces you don't want it to stick to.
The solution to that is to cover the surfaces with blue painter's tape, but
don't cover the joints where the glue will come out or it'll just push the tape
off and get all over where you don't want it.
If you do use that glue, you need VERY SMALL amounts. A few tiny drops will do
the job and don't forget to protect the foot's outer surface with the tape.
