i have great arches but love my crocs as well. I had bought dickies brand but my feet hurt so bad (Plantar Faciitis). So, mom bout me birkies, they were MUCH better but my heel pain got out of control. I had to buy ice bags and strap them on my feet on the ride home from work one night. SO, on a whim I tried the crocs. Though I have mild mild pain still after work and in the am, I get through work no problemo. They aren't for everyone, but that is my experience. I can no longer wear my tennis shoes either
