I was extremely disappointed with this product.  The shoes looked as sleek and well constructed as advertised, but they were extremely uncomfortable (as many new shoes are) to break in.  Within a month or two, I noticed an extreme amount of wear, and I only wore them from my car to my office and vice versa.  I am going to email the customer service support team to seek reimbursement or replacement.  I have had several pairs of Calvin Klein's that lasted over a year, so I question the authenticity of this product.
