I want to order a pair of Vibram sole trail oxfords really soon but I'm still so torn. I'm pretty much a US8.5D in any dress shoe. 8.5 in Clark Desert Boots, 8 in Alden Indy Boots. Some salesman quickly measured me in a brannock device a while back and said I was an 8D which I'm not sure I even believe anymore. I want to wear these in the warm weather without socks. Oak Street tells me stick with 8.5, SF logic seems to be absolutely size down .5 What do I do!!!
