I’m getting the cast off my foot 3 days before leaving for burning man. I’m super excited because I’ll be weight bearing in a special walking boot. I’ve got a trike so I’ll have extra stability for tipsy riding

I’ll bring my crutches just in case and not be stupid and try to climb things or jump up and down dancing, some of my favorite BM pastimes.
Any tips from people that have experienced the burn in a walking boot or cast?
My biggest question at this point is - how do I not get it disgusting? Im getting pleather socks to keep the dust from my foot (which will probably feel disgusting and hot but it’s better than Playa foot.) I’m going to buy a second one and decorate them both. However there is a lot of cushy exposed fabric and Velcro to it. I just imagine it’s going to be a dust magnet. I was imagining maybe I could get creative with some leather around it, but I can’t fully enclose it because I’ll have to have access to take it off.
Any ideas?
