The real differentiator between these surfaces isn’t just “fast vs slow”—it’s the ratio between your static (stiction) and kinetic friction coefficients. On cloth, you get a high peak static CoF followed by a sharp drop to kinetic, which is why you can snap and stop dead on a dime but pay for it with micro-jitter and more arm fatigue over a long session. Glass is the opposite: the static and kinetic coefficients sit much closer together, so there’s barely that “catch” before movement begins. This is why glass feels like it skates but actually stops more predictably once you’re already moving—great for micro-adjustments in tactical shooters where consistent tracking beats raw speed. Cordura sits in the middle as a wear-layer treatment; it’s really about surface durability and a slightly more consistent glide than raw cloth, but it degrades as the weave wears down over hundreds of hours, which shifts your CoF gradually.
On the hardware side, don’t sleep on how much this interacts with your base weight and feet. Glass pads demand more downward force to overcome that low friction—most glass pads like the Skypad or Artisan Zen run 85-95g themselves, so if you’re underweighting your mouse you’ll feel floaty and lose that tactile feedback on stops. Also worth noting: glass is temperature and humidity sensitive. In a cold room the surface feels more “sticky” and higher friction; run your room warm and it drops
