4 Things to Know About Glass Mousepads and PTFE Feet

Glass pads wear down PTFE feet much faster than cloth pads PTFE is a soft polymer, and glass is hard and non-porous. Expect to replace feet every few months instead of once a year.

The friction comes from microscopic texture on the glass surface Even polished glass has a rough surface that grinds against PTFE feet. This friction shaves off material over time.

How fast feet wear depends on the pad’s coating and your mouse setup Standard PTFE feet can go from smooth to scratchy in 2–4 months on glass, versus 6–12 months on cloth. Some “infinity” glass pads with special coatings are gentler but still wear faster than cloth.

The trade-off is worth it only if you are ready to replace feet regularly Glass pads feel consistent, stay clean, and don’t develop slow spots. But if you are not prepared to buy replacement feet often, stick with cloth.
