I'm a 10 1/2 EE, but I've always had to size up by half to 11 4E in New Balance shoes. These boots changed that. These boots were so tight that I might have to size up by triple to achieve a proper fit. Hard to understand how New Balance sizes these boots. They might as well throw out the traditional US shoe measurements because they're entirely inapplicable. In terms of quality, the boots appear to be well-made, but that's a very superficial judgment as I only had them on my feet for about 10 seconds. If you've got the time and patience to endure order after order until you arrive at the right size, go for it. I've come to depend on New Balance for it's quality and foot support, so for me it's worth the slog of spinning the wheel of fortune again and again. At present, I'm waiting on a 12 4E to see how that fits. If not, on to a 13 4E, if I can find a pair of those.
