I have owned many types of Merrell shoes, sandals, thongs (flip-flops), but from day one these are the most uncomfortable things I have ever had on my feet!!! I am not sure what I can do with them now, I thought at first they just needed to be broken in, like most shoes do, but my feet were the ones that tried to break into the shoe, so now after 3 or 4 weeks I have had to give up on them.  I am a tour guide and walk about 7 miles a day, so shoes are very important to me. I wanted these to work, they look great, BUT they are now just taking up space in my closet.
