Step 2 Remove the feet

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.

Step 3

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.

Edit

Step 4

Peel up and remove the foot.
If the rubber layer separates from its adhesive pad, use the same process to remove the pad.

Edit

Step 5

Repeat the last three steps to remove the remaining feet.
If you're just removing the feet to open the mouse, you don't need to remove the two angled ones near the sensor or the larger one on the outer edge.

To install a new foot:
If any of the feet got damaged during removal or separated from their adhesive pads, replace them.
Use a spudger to carefully scrape up and remove any remaining adhesive bits.
Use isopropyl alcohol and a microfiber cloth to thoroughly clean all adhesive residue from the foot recesses. Allow the surface to completely dry.
Remove the feet from their backing and firmly press them into place.

Edit

Step 14
