the shoes are very, very uncomfortable!!!  there are seams where the shoe is put together on the top straps and they rub your foot.  i couldn't even wear them an hour.  no paper work came with the shoes and i don't know how to return them--they were too expensive to just let them sit around.  what do i do to send them back to you?  i was really disappointed because a friend just raves about Merrell shoes.
