Here is a picture of the original Maseur Sandal. They have been discontinued. A new company took over the production, but the quality wasn't the same. These were the best massage sandals ever.
There are, however, a couple of decent alternatives that I have been able to find out there. These include Adidas Assage, and Old Friend Beachcomber Sandals. These are available at zappos.com, as well as other online shoe stores.
Other Reflexology Sandals exist, but I have not tried any additional brands so far other than Maseur, Adidas and Old Friend. I will keep looking. And, it is good to know that there are still some quality alternatives to the original Maseur - but I still miss them!
UPDATE: I have been wearing both the Adissage and the Old Friend Sandals for some time now, and truly like them. The Adissage is especially nice as it is well made and really holds up to wear - and it's a really great price!
