I have been trying on the 10.5 D's I got from Zappos for a week or so now, wearing them about the house. I have realised that the issue I will likely have is in the heel. the mid foot is a bit snug, but wonder if this will break in? So, yesterday zappos go the EE in in 10.5 so I plunked down another $300 and ordered, luckily they are all returnable, hopefully the wider width is as Neognosis says above is really the true "D"...and not too wide for me...I really like they quality and styling of this boot. The wolverine Montgomery I had tried seemed less "ulilitarian" and more "fashion". This seems like a solid boot.
