the shoe is really nice and on the whole I'm fine with visible chunky zips on clothing, but not on a smart shoe. If it was a casual shoe then yes. On the other hand it's pretty unique and they still look smart so go for it if you like.
It's the sort of shoe I could imagine Primark selling an imitation version of, for about £12. So no, don't spend that much on them! I also don't like them that much :P The zip would make them too casual for work IMO (and for that price I imagine you don't want them for a night out?!)
