Should I size up in the Solovair Classic 8-Eye Derby Boot for thick socks or break-in?

Break-in: Firm leather 5â€“10 wears, then molds; often kinder than stiff Docs for some feet. Thick socks add volume — try the sock you will wear with the usual size advice before jumping a full size. See the thick socks & boot break-in guides.
