My only heart ache regarding these wonderful shoes, is that as I work long hours on concrete they will have to be replaced long before I'm willing to give them up!  I am certainly going to keep re-ordering this model.  Best shoes for working retail.  Light weight, flexible uppers allow room for my low set ankle bone (which usually pains me in most shoes) while providing a wonderful air flow.  This is the first shoe that I've ever felt really comfortable in without socks.  I live in these at work and at play, I've even taken up extreme hiking without a concern over whether they will hold up.  The sole bed on these are amazing, with plenty of shock absorption and the support they provide has already made me feel like a brand new woman.  I'm no longer aching and just wanting to sit by the time my shift ends!  I know this sounds ridiculous, but I'm so much more active now that I'm comfortable, I've already dropped 10 lbs.  p.s.  These are awesome shoes for water as well!  The soft, breathable uppers remind me of a water sock, with material that breathes very well, and therefore, dries quickly.  See?  They even go to the river with me.
When I ordered them I remember shaking my head over the promised delivery time... but would you believe they arrived a full day earlier?!  Could not believe the speed in which they fulfilled my order.  I've got to end this now, and start deciding which color is going to be my next purchase.  :)
