Thanks for posting that because I wanted a chance to brag about my own new sandals. I got the SAS Bravo, and it's totally comfortable right from the git-go. Haven't done long, hard walks in them, and probably won't. The places I go for walks have gravel and loose sand, which has been an issue with every sandal I've owned.
They look remarkably like Birkenstocks, but the resemblance is superficial. Birkies have your heel lower than the ball of the foot. More comfortable foot bed, too. I've never been happy with that, and a name brand physical therapist confirmed my impression. Also, SAS uses a very soft, lined leather for the uppers. List at $140.00, but the local shoe store found out they couldn't move sandals at that price in this town, so I got them at $70.00.
