Sorry, accept the wise comments but do still love the designs of both of these and think they're really pretty - but can't decide which to try on, let alone buy. I do already have a couple of pairs of skate-type shoes, which I do wear a lot and really like (silvery ones by Geox and a German make). However, don't know whether that means I'd like the Ash better or that I should have a change from the style!
On smart casual, used the wrong phrase - I meant the sort of thing you'd wear to a summer barbecue, which isn't necessarily what most people mean by the term I guess.
