This is the first pair of Grasshoppers that did not fit comfortably.  The fit was good except for the heal.  Not sure what the problem was, but I couldn't even wear them for 5 minutes before my feet were hurting so much I had to take them off.  I tried a couple weeks later and it was the same.  I've never put them on again.  They are sitting in the box, never worn.  Thoroughly disappointed.  I've bought these from regular shoe stores and never had a problem.
