Another thanks for the review. I too, have been looking at the Kinvara...for over a year now, but have yet to pull the trigger on a pair. I've been fairly happy in my Nike Free Run, but just this week started to get some familiar toe pain/numbness (which is usually my signal that it's time for new shoes). So today I ordered a new pair of the Nike Free Run 2 (new version) from Running Warehouse. I'm hoping they will fit exactly like the previous incarnation...but if not, then I will try the Kinvara. I too, need a wide toe box (hammertoes) with a narrower heel. I did try on a pair of the women's Kinvara at my LRS...I tried a size 10.5 and I thought it felt a tad bit narrow in the toe box...my toes felt a little squished. I haven't tried the men's version though, so I'll have to do that. In the Nike Free Runs I wear a women's size 11, and I have lots of toe wiggling room.

Does the Kinvara have a traditional tongue? It's been a while since I last tried a pair on, and I can't remember if they did or not. That is one of the characteristics about the Nike Free that I love...no tongue to move around and irritate the top of my foot.
