For those wondering what to use and on some models - how to cut the holes out.
it's called grip tape and is used on skateboards - so easy to come by on that auction site.
Cut to shape with old scissors or a stanley knife.
if you need to cut holes, then mark them from the underside in pencil. I just traced round them on a flat surface after marking 1.5" in from the edge.
I then made punch from a piece of chrome pipe - turning the edge sharp on the lathe, and then with a hammer on a piece of rubber mat they were cut through.
and voila... Bendy has grippy footplates
