I was hoping to like these shoes after reading the good reviews.  I wear a size 11 in nike running shoes and never had a problem ordering online. So I got a size 11 for the air max.  When I got it the shoe felt too tight and somewhat narrow.  Maybe I needed to break them in first, but I didn't as it didn't feel right when I first put them on.  Plus if I walk around in them for a while, I couldn't get a refund.  I returned it and got a size 11.5.  I got those shoes and at first they felt great.  I decided to keep it.  After taking a long walk, the shoes started rubbing against my heel.  I ended up getting blisters.  So 11 was too tight and narrow and 11.5 was too big...  So now these shoes go in the closet.  First pair of nike shoes that didn't work out.
