Right, thanks everyone.
Anna, I think those boots are not quite what I'm after, a bit dressier than what I had in mind.
If the Duo ones have big feet, I'm a bit wary. Don't want to avoid the wellies situation only to find I look like Big Bird.
Shame, as I liked the look of the Brindisi ones.
The heel on the Kirov is not really what I'm after, as I carry DS2 about in the sling a lot and wanted a flatter, wider heel.
The Ravenna look nice, as do the Oristano and the Pavia.
Am a bit at the returns policy, though. Returning them by TNT at a 'very competitive price' sounds potentially expensive. If TNT charge 21 euros for a passport, what must a thumping great pair of boots cost?
Am going to mull this over a bit more.
Castille, I'd never heard of Na! (don't seem to exist down here in the south). They have some nice stuff.
