Competitive use benefits most from a predictable surface and enough uninterrupted movement area.
Arm aim at lower sensitivity normally consumes more pad width and depth. Wrist-dominant movement can use a smaller area but may prefer a different friction balance.
Initial friction affects how easily the mouse starts moving, while dynamic friction shapes glide once in motion. A pad can feel fast in one measure and controlled in the other.
PTFE, glass and aftermarket feet respond differently to the same surface. Hard feet on hard pads can increase noise and change wear.
Some cloth weaves change feel as moisture and room conditions vary. Hybrid or treated surfaces can behave differently but still need appropriate cleaning.
A soft pad can arrive curled and need time on a flat desk. Do not apply high heat or force unless the maker explicitly allows it.
Speed and control labels have no shared industry scale, making material and measured comparisons more useful.
