Hey everyone, this forum has been pretty informative for me so I thought I'd chime in and share my experience. I just picked up a pair of Danner Overtons in a size 12, but before I comment on them here is some of my size info for reference. Someone brought this up earlier and I think it helps with those searching for the right size.
Danner Acadia and Danner Marine Hot- 12
RedWing Style #875 Boot- 11M. A little narrow and probably could have gone with wide, but not a major issue
Frye- 10.5 D/Med- they run a bit smaller than the RW for me. I ordered and 11, but sent back for a 10.5
Running Shoes- 12.5 in Nike and New Balance, and a 13 if I go with Brooks.
That said, I'm a little bit all over the map with my sizing. I ordered the Overtons from Danner's Breakroom and went with the 12D even though they suggest sizing down a half size due to the wide 650EE last--I figured I could make up the additional volume with an insole. This is where I get a bit confused--Danner sells boots in the this "wider" last in a D width and also a EE width (look at the Danner ML II). I thought that if you got a boot with a wide last (650EE) and went with a EE width that you would just get a super wide boot. Anyyyywaaaayyyy, I found that the the 12D fit me great and I did not find them any wider than my Acadias--strange I thought. I agree with an earlier poster who said that the width will not change the length of the boot--at least in my experience it has not although others will advocate going down a half size. I prefer an insole with my Danners and go with a superfeet orange on my Acadias as these are my military boots and need them for field work, rucking, etc. Not the case with my Overtons as I prefer a looser fit with these since they will be more of a casual boot for just kicking it, camping, very light hiking, and walking around town. So I went with Pedag leather insoles for my Overtons--some here may want to check them out. They are very thin an comfortable and are design for shoes that do not come with a removable insole--they take up very little volume. All-in-all the Overtons are an outstanding boot and I love the fit. My experience is they fit TTS, but if I got a boot in the same last (650 EE) and a wide size EE in a boot like the Mountain Light II, I would still go with the 12 and get a superfeet insole to fill any extra volume. Hope this info gives some useful frame of reference for you all
