Glass mousepads will eat your mouse feet faster.

Yes, glass is harder and more abrasive than cloth, so it wears down PTFE (Teflon) feet faster. It’s not a myth.

The trade-off is simple: glass gives you a slick, consistent glide that feels amazing for fast flicking, but it comes with a shelf life for your skates. Cloth pads are gentler and let feet last for years, but they collect dust and wear unevenly over time.

You can slow the damage on glass by using thicker feet (like the “glass” or “speed” varieties) or replacing them every few months. Some people even use ceramic feet, but those can scratch the pad itself.

If you’re not willing to swap skates occasionally, stick with cloth. If you want a near-zero-friction surface and don’t mind buying new feet, glass is fine. It’s not a dealbreaker—just an ongoing cost.
