Very nice garb!
The shoes will come. Do you have access to Ithra classes? Since they teach pretty much everything (would not be surprised if there's a class on how to build a kitchen sink), there might be someone who can teach a class on shoes.
Mind you, if the rubber part was black instead of grey, I don't think anyone would even notice, or at least not enough to warrant a fuss. I always wore either runners or my black winter boots at outdoor events, since it wasn't unusual to get at least rain and I didn't want to risk my beaded and embroidered indoor shoes.
I'd learned my lesson at an outdoor demo in early September when it started to sleet and we gave up on the demo. We'd brought enough food to feed us and anyone who showed up to watch, so we called the one person in the shire who wasn't there that day - she was at home, packing to move. We just phoned her and said, "We got sleeted out of the demo, and we're coming over to your place for supper, we'll bring the food." It turned into a nice going-away party, complete with dancing in the basement.
