Hahaha, honestly, I had the hardest time driving with shoes ON.

But then again, I come from Hawaii, and grew up on Kauai, where I would never wear shoes at all, and even when I moved to California for a year I didn't wear shoes even during the winter. Got sick from that, but that didn't stop me. Up until it was required I went barefoot all the time, and then slippers after that.

To me it was always I could feel the pedals way better barefoot, and in the beginning when I drove with shoes I was always scared of pushing both pedals are once.

However, it sounds like your daughter doesn't have tough feet, kinda like what Ose was talking about. If your daughter is worried about hurting her feet, then heck yeah don't let her drive barefoot, but otherwise, barefoot it up

Might be a Hawaii thing as Kona-Vs has said the same thing.
