Here's a funny update. I ordered the Buttero brown suede workboots Thursday night; I liked the sale price. Friday night I got a shipping confirmation, but didn't bother clicking on the FedEx link. Anyway, after reading this thread and doing some searching regarding sizing on Sufu, I opened the e-mail and clicked on the link to see that the boots were delivered today! Granted I am in upstate NY, but damn! So I ran out on the porch where they've been sitting since 2:16 this afternoon.
As far as the sizing goes, I went down a half to 9, and I should've gone down a full size. These things run BIG. I matched them to my Brando Engineers which are also a 9 and these are a good cm longer. Guess they're going back.
