Replacement rubber feet for 50g

By chance, I had some glue to repair neoprene suits: it is like contact cement. It is pretty stable and elastic on neoprene, so I felt it was a good option for an elastic union with the rubber feet.
The result is very satisfactory after applying the glue: now let's see what happens with time.

[Edit:]
No luck with the contact-cement-style glues (standard or for neoprene). The glue doesn't stick to the rubber foot: it is easy to peel-off from the rubber's surface. So I had to go for the Super Glue (cyanoacrilate). It's more aggressive with plastics, but apparently it works. A very tiny amount must be applied to the foot socket, to avoid leakages around the edges of the socket when introducing and pressing the foot rubber. I used a toothpick to spread the tiny amount of liquid glue. The result is very clean: again, let's see the durability.

I use double-sided sheets with a very powerful adhesive on both sides. I peel some backing off one side, stick a foot to the exposed side then trim around the foot with an X-Acto knife. This leaves the foot with paper on the bottom. When I'm ready to mount the foot, I peel the paper off the bottom of it and carefully place the foot on the calculator. You only get one shot at it so you have to be careful to align an edge first. Once I finish putting the foot on the surface, I press it firmly, just to make sure. It's on there permanently and there's no mess or possibility of ooze.
