I don't know Wolverine sizing enough to say, but I find they run about 1/4 size large actually. I'm anywhere from an 11 to a 12 depending upon the shoe. Running shoes are all 12, Alden boots in Barrie and Trubalance last are 11s. I have White's in 11 and 11.5 and the 11s are a little short such that my toes do touch the end after being on my feet for a bit. This works because those boots are soft toed but I'm not sure I'd be comfortable in a firm toed boot in the 11. The above applies to the standard Semi-Dress last. I do have one pair in 11 on the Swing last as well and that fits a touch longer in my experience and I have room at the end in them. If you've never ordered before...do foot tracings and send them into White's. As long as you do the tracings and measurements properly they'll get you into a good fitting boot.
