I think that's the Guidi e Rosellini line. Different models, most of which have rubber soles.Actually, I've been curious about this line as well, it's not much discussed but I really like the derbies I have seen.
I just noticed that the Elodea sweater from Schneider that I had saved in my wish list seems to be completely gone from the website. Will it be back? (and if it comes back, how is the sizing compared to the Poa cardi?)
