Received today (Hot in NJ)for 4th of July weekend. Right out of box very comfortable,light,very adjustable. I have VERY WIDE & FAT diabetic feet. I've paid the same or maybe more for sandals that are bottom heavy and tire my feet, these don't. The negative heel impact on these sandals are a plus even when standing. The footbed feels good to my feet when walking. Good structure, hope to reap other benefits of posture, balance etc. Great buy. Blue-sold out, will go back for the green.
