Lisa, from my experience I do not mind buffing off gels - especially on the toes nails, as they have only a thin coating of gel. If you are experiencing a client with misshaped toenails, I would buff the gel until it is flush to the natural nail plate and reshape the free edge (leaving a small amount of gel on the natural nail) then leaving this to grow out naturally (your client will not even see/notice the very fine gel).
