Shoe Care

I'm no help when it comes to cleaning ideas, but I would definitely suggest putting non-slip skid pads on the bottoms of the shoes to eliminate the slipperiness!

Take a knife to the sole and make some # shapes - that helps. I would avoid wearing them outside before your wedding, that's going to be the easiest way to get them dirty.

I agree you should scuff the soles so you don't slip. As for cleaning, lace should be spot treated. Start with soap and water, then move on to stronger cleaners (like vinegar and baking soda) as needed. The pleather should be fine with soap and water, or even just water.
