What type of mouse pad is easiest on mouse feet?

Soft cloth pads are easiest on mouse feet. Hard pads like plastic, glass, or aluminum shred PTFE feet faster because the hard, rough surface acts like sandpaper. Cloth pads have a yielding, woven surface that causes less abrasive contact. For longest foot life, use a fine-weave cloth pad like a Steelseries QcK or Zowie G-SR.
