This is a great lightweight sandal for those who like to walk in the summer, but don't like to wear clunky sneakers!  I've worn these shoes everywhere since receiving them earlier this week.  Yesterday was a one-mile walk with the dog around the park.  My feet felt great and I could've gone another mile!  No blisters, no arch discomfort.  They are cushioned in the heel and the shock is absorbed very well.  Another reviewer mentioned back issues, which I also have, and yes my back does feel good today, even after that walk.  I am a size 8 and ordered a size 8.  They are a touch on the long side, but a 7 would've been too short.  Actually when I'm walking downhill I'm grateful for that extra room because the toes do shift forward.  At Amazon's price, at least give them a try!  Much cheaper and a much better walker than Teva.
