How Long Mouse Feet Last and How to Tell It Is Time to Replace Them

In short: there is no exact lifespan: on soft cloth feet can last from several months to several years, on hard surfaces and with intense play, less. Go by the signs: scratches, uneven edges, noise, changed glide and visible wear.

What does lifespan depend on?

• Surface. On glass and hard pads feet wear faster than on cloth.
• Cleanliness. Dust and particles act as an abrasive.
• Play intensity. More hours, more friction.
• Mouse weight and hand pressure. A heavier mouse and firm pressure speed up wear.
• Material and thickness. Thicker feet of denser material usually last longer.

Signs it is time to replace

1. The glide feels different. The mouse "drags" or glides unevenly.
2. Noise or squeaking appears.
3. Wear is visible. Edges are worn down, burrs or scratches appear, the foot has become thin.
4. The mouse is tilted. One foot has worn more than the others and the mouse "drifts".
5. Feet are peeling. The adhesive has lost grip.
6. The sensor behaves unstably. Worn feet reduce the distance to the surface, see why the mouse jumps.

How to check

1. Turn the mouse over in good light.
2. Compare the foot edges: they should be even and of equal thickness.
3. Run a finger over them: there should be no sharp burrs.
4. Put the mouse on a flat surface: it should not rock.

How to extend lifespan

• Keep the pad and feet clean.
• Remove dust and hairs from the feet with a soft brush.
• Do not use the mouse on a dirty surface.
• For glass use glass-specific sets, see glass mouse pads.
• Do not scrape the feet with hard objects.

How to replace

1. Carefully peel off the old foot (you can warm it with a hair dryer on low).
2. Clean the adhesive area on the body with an alcohol wipe and let it dry.
3. Stick the new foot on straight, not covering the sensor.
4. Press down and let the adhesive set for a few hours.
