Query: Not Birkenstock - just a look a like

I was very hopeful when I saw these, since they are licensed by Birkenstock......But......I have worn Birkenstocks for years. I ordered the size the size I have always worn. When I kicked off my old birkenstocks to put on my nice new ones, I couldn't even get my feet into the shoe. They are very strict on returns you can't cut the little white thing that holds the shoes together. You have to return within 15 days, and your charged $6.95 restocking fee. The one postive thing is they ship really fast, I just wish I could use it.
