Ruth's sister mouse feet for MX 3S 2 packs black

Replacement feet for MX 3S mouse

These PTFE mouse skates are cut for the MX 3S and ship as two full sets in black. They lower friction against the pad so the cursor tracks more consistently during work or play. The 8 g pack adds negligible weight and the feet sit at a height that prevents bottom scraping. Installation is a simple peel-and-stick process.

Check mouse model and surface

Verify that the mouse is an MX 3S before ordering because the cutouts match only that shape. Clean the sensor area and the old adhesive residue thoroughly so the new feet bond evenly. A hard or cloth pad works, but a heavily textured surface can wear the PTFE faster. Ensure the feet sit flush after application to avoid sensor interference.

Upgrade from worn or stock feet

These replace factory feet that have become scratched, uneven or peeled after months of use. The jump is worth it when the mouse starts to stutter or drag across the pad, restoring the original glide feel. They also refresh a second MX 3S without buying a new mouse. Users who prefer a different glide characteristic or need a third set should look elsewhere.
