Slide an opening pick under an edge of the bottom mouse foot.

Go slowly, and make sure the pick is underneath both the foot and its adhesive layer if you want to reuse the foot. It's easy to separate the foot from its adhesive.

If the foot feels stuck, apply more heat before continuing.

Slide the pick under the rest of the foot until you can lift it off the mouse.

Remove the foot.

Repeat the procedure to remove the top mouse foot.
