Best sandals I ever bought and I have at least 50 pairs to match my clothes.  Wearing them on the sand on the beach, on the cement, on the tar, on gravel, just about anywwhere and your in comfort.  I have used them all (I bought 3 different pairs) and they are just perfect.  No blisters, not cuts, no scrathes and for someone diabetic who needs to make sure they take care of their feet due to gangarene, these are the best.  Buy them...you'll love them.
