Just got my women's Montrail AT Plus this afternoon and discovered that while a size 10 fit me perfectly in the old 2007 Hardrocks, size 10 is definitely too big for me in the AT Plus. The AT Plus don't look as quite supportive as the old Hardrocks, and the upper in the rear is less stiff. I can't really tell if they'll work until I get a size 9 1/2. I'll report further when I try the right size, but at this point I'm a bit dubious.
