Raised foam wrist rests usually create a catching edge.

Yes, if it’s a separate pad with a foam rest glued on top. The transition between the foam and the mouse surface is almost always a raised lip. During a large sweep your mouse catches that edge and either stalls or jumps. It’s infuriating in games and annoying in precision work.

Some expensive integrated pads (like the Glorious Wrist Pad or Razer Strider with gel rest) eliminate the lip by molding the wrist rest into the same surface level. But those are the exception. The cheap Amazon combo pads are all two pieces stuck together, and the foam sits higher.

If you need a wrist rest, get a standalone one that sits next to the pad, not attached to it. Or skip the rest altogether and focus on a lighter grip.

Your aim will thank you.
