The feet are secured to the bottom of the mouse with adhesive. In order to cleanly remove them, the adhesive needs to be thoroughly heated.
Heat an iOpener and lay it on the mouse feet for one minute to heat the adhesive.
Alternatively, you can use a hair dryer on the Low heat setting to soften the adhesive.
If you're using a hair dryer, only heat the feet a few seconds at a time or you may warp the plastic shell.

The feet have two layers—a rubberized one and an adhesive pad underneath.
If you're reusing the feet, be very careful not to separate the two layers or damage the feet.
Carefully slide the point of a spudger under the large foot near the front of the mouse, making sure it goes under both the foot and its adhesive pad.
The foot recesses have a small notch that makes it easier to slide your spudger under.
Gently slide the spudger farther under the foot and lift until you can grip the pad with your fingers.
