/cgl/ - Cosplay & EGL

Hi there /cgl/. I'm doing a cosplay which requires these shoes. Is there a way to change these so that they're more comfortable or am I stuck doing the whole "I'll switch shoes whenever someone wants a picture" deal? Like are there cushions I could put in or maybe even carve some sort of foot-shaped-groove in them? I want to be able to just wear one pair the whole time because it feels more genuine. However, after hours of walking around I'm sure it would be understandable to throw your pride out the window just so your feet will stop hurting.

Also I guess I got the cheap kind (thank you ebay) and these are made of plywood or something. They chip very easily. What can I put around the edges and bottoms to make it so it doesn't chip? I was thinking getting sticky velcro and putting the fuzzy side on the bottom so it would help at not be too noticeable. They also slip on hard floor a bit, despite the rubber bottoms. Is there any way to make it less dangerous?

Thank you in advance.

tl;dr
How can these shoes be more comfortable and what can I put on them so they won't chip or slip on the floor?
