Thanks for posting Desi, you said what I should have said, but you said it better than I did. I'm not busting on the other shoes, I'm just saying they don't feel very good on my feet.
When QVC sold Birkenstock shoes over the years I bought (I swear to you) over 100 pair of Birkenstock shoes. Some were clogs, but most were all different designs of sandals.
I would order the other brand from HSN (they sold them) and they never felt good. I kept some of them but never wear them. I think there is a difference. They feel cheaper to me.
