Why is it not a good idea to use Sperry? I think that is a much more pointed observation than "dress shoe size." Most dress shoes run off the brannock, but not all dress shoe sizes are the same - there are hundreds of brands out there. The reason people started talking Sperry sizing is because it is a ubiquitous brand everyone can try on. I've had and tried on many different Sperry boat shoes and they all fit me about the same. If my foot fits perfectly in a Sperry size 9, and someone else's does as well, you can pretty surely assume our feet are about the same size as one another. I actually think this is a much better way to discuss sizing issues than "dress shoe size." The brannock measurement should be a good way to determine sizing, but mine ran big for brannock measurements, as did others that are actively discussing right now. I honestly think picking a brand and discussing sizing in comparison to that brand isn't such a bad idea. I don't see why it is any less accurate than the above stated. Comparing your sizing to sneakers wouldn't work because they are padded and worn with socks, but Sperry, worn sockless, although not anywhere near the quality of these, at least have good quality control and people know their size. I really think the only people weighing in on this should be those who have had these in their possession and tried them on. For a six week wait, you telling people to order their dress shoe size or brannock size could mean a return. Since you are just going off what George said, the same as he told me originally - which didn't work out, I'd say wait until you receive them. Obviously everyone's foot is going to fit a bit different. because all shoes are made differently. the reason why people refer to dress shoe sizes is because you generally dont find the same variances in sizing as you would find in something like a sneaker, which is all over the map. buying shoes is extremely difficult especially those on-line and especially those you cant see and have to order right the first time. this is why, at least to my understanding, george had the lasts created to match a brannock device so peope could safely order a size and know it will fit. you can certainly go on all you want about x, y, and z brand but i dont think it will help people, especially since most of the guess work is really taken out. does that make sense?
