I had the  old striped version of the Blackwing and they were inside a backpack that got stolen from my car. I ordered the same size as the last pair but these seem to have a little more room in the heel.  The old heel fit perfectly, these have a tiny bit of air but its not the end of the world. The shoe still fits great, maybe a little roomier over all.  I ordered exactly my street size.  They perform incredibly well.  I feel like I am cheating when I put these puppies on!<br />My only criticism would be the color.  Not every woman wants to wear pink.  I've worked in outdoor retail for 20 years and I wish vendors would learn this. I loved the old striped ones.  If you have to offer pink, make it an optional color, not the only color you offer. I'll wear these happily, nonetheless, because they perform so well.
