This is the first pair of Clarks Unstructured that I have owned.  I am ready to buy another.  I am on my feet pretty constantly in my sales position and walk an average of 3.5 miles per day.  These shoes are amazing.  My only concern will be is how they hold up over time, but my first impressions are excellent.  I am concerned that Amazon is dis continuing this product.  I hope I am wrong.
