This is one of these "I wish I'd bought them at the time" scenarios!
In London, in the summer, I tried on a really comfy pair of pumps. They were in the sale, but still quite expensive so I didn't buy them immediately. I then decided to get them on my way back to the station, but I didn't realise that shops in England stay shut till 11am on a Sunday. 
They were, I think Geox (if that's in Covent Garden) but possibly Ecco.
The were soft, black suede, but textured like fish scales with a a slight shine - I'm not explaining this well; they were almost shimmery in a certain light.
I've checked both the websites, but if anyone could find me a name, I could look on eBay.
Sorry for the crap description, but if there are any S&B sleuths about, I'd be grateful. Thanks
