I have a similar issue, I'm cosplaying as Inuyasha soon and he doesn't wear shoes. I just recently found a thread on here
about how to deal with it and I think the best suggestion there (at least for my situation) was invisible shoes.
I haven't tried it yet but they are basically transparent PVC insoles with mesh fabric straps that you colour to match your skin colour. Here's the tutorial
on how to make them if you decide to go for that idea. Anyway good luck
