Thank you. Leather would be idea if I didn't risk bodily fluids getting on them. I don't know how easy they are to clean. I don't want to end up ruining a pair of BIFL shoes by trying to get urine or feces out/off of them. I also have to give showers and sometimes my shoes fill up with water running off my legs instead of getting sprayed on the shoes where waterproofing would come into play.
