I found these Ace Attorney stickers today!
For that hobbit cosplayer: They actually make flip flops without the top thong part. I'm not sure where you buy them (maybe Google it?) but they have like a sticky part you just wet and then you step on them. Instant feet cover again and again. Only problem is since you stick your whole foot onto the pad, you can't wiggle your toes which was a major problem for me, but if your ok with that it could work and give you the foot cover while looking like your barefoot. Good luck!
