These were the most comfortable shoes I have ever had on my feet.  However, after 2 weeks of just walking (not even running) the webbing over the toes gave way.  I went through the process of getting a return authorization (within their 30 day return policy), paying for shipping and returning.  I never received acknowledgement from Dress Code Clothing that they had received the return.  USPS tracking did inform me that the shoes had arrived on 10/10 (5 days ago).  I requested an exchange of the defective shoes.  I had not heard anything from the company and called a non-toll free number today and was told that they had received the shoes but they would not replace them because they had been "worn"! I asked then why I hadn't been notified of this and why hadn't my shoes been sent back. The "service person" said I should have been notified.  I was told that "now" we will send the original shoes back.  I was also told that there was no supervisor to speak with.  I have never had bad service from Amazon or one of their partners, but this experience is very disheartening.  I certainly will never buy shoes from Amazon again.  Zappos!, here I come!
