Flip-flop paw base

Has anyone actually used flip flops for fursuit feet with success? I see a rising trend in it and honestly can't imagine how you'd go about foaming and furring some feet to a flip flop sole.

I do have my clients send me comfortable close-toed shoes when they commission me, but I want to work on some pre-mades this summer and I think this may be a nicer alternative than losing my fingers cutting out stiff foam mats with scissors.

Thanks!
