Maybe the foot slipped. I just don't know where you could prove it, without asking the guys exactly what happened on every error, and attribute it to the guy running. It is just something we assume because guys "rush" things when a fast guy is running versus a catcher.
You'd almost have to break this into 2 categories... new errors, and capitalizing on errors that have already occurred. It goes without saying that speed forces errors, because it capitalizes on them, I can picture quite a few times where a shortstop bobbles or drops a ball hit by Bo Diaz...only to then pick it up and throw him out anyway, it's only an error if the runner gains something from it. Just like a player would get more infield hits due to speed, he'd get more infield errors, without having a "new" error exist.
