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

Go slowly, and make sure the pick slides underneath both the foot and its adhesive pad. These layers separate easily.

If you plan on reusing your mouse feet, be careful not to crease them or separate them from their adhesive pads.

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

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

Peel up and remove the left mouse foot.
