My friend has got two pairs, I think, and she has never experienced them getting dirtier than regular boots or shoes. As long as you don't deliberately walk into mud puddles, I think you'll manage. I borrowed one of her pairs once in fact, and they're sooo warm <3 They're not my style, though, so I hadn't worn them if my own boots hadn't been totally soaked (but then again, hers hadn't, so they keep water out). But you should totally wear them if you want to!
