UNGLUED SOLE.  I purchased three pair of these the past few years after suffering from plantar fasciitis.  A bit pricey but I liked the support, fit and feel and figured they would be a quality sandal.  After approximately six months of wear, the sole of the sandal began to open up in the front, ungluing from the foot bed, creating a dangerous front facing flap. Apparently the foot bed/sole is two layers glued together.  This eventually happened to all three pairs and regluing attempts did not work.  I contacted the manufacturer a week ago and all I received was an auto response message.  This would be a great sandal if they could make the sole out of one piece of vinyl/rubber.  $180 in the trash. I will look for another brand and cannot recommend.
