Push the tip of an opening pick underneath the mouse foot adhesive, into the gap in the rim.

Slide your pick under the foot to separate its adhesive until you can grab it with your fingers.

Repeat to remove the three remaining mouse feet.

Use a pair of tweezers or a spudger to remove any large chunks of leftover adhesive. Thoroughly clean the bottom of the mouse with isopropyl alcohol and a lint-free of microfiber cloth. Allow the surface to dry completely.

Peel your new mouse feet away from their adhesive liners and press them firmly into place.
