**update** I received my replacement shoe and have been wearing them for a little over a month now. They are a comfortable shoe and I can wear them all day long without any kind of pain or fatigue in my feet, which is great. However, they are made of low quality material; the rubber tread on the bottom of the shoe started peeling off after only two weeks; also I use the loop in the back to pull the shoe over my heel, and the loop ripped causing the entire  back of the shoe to rip; in addition to that, the entire rubber sole is beginning to detach from the fabric of the shoe. I am still wearing them, and they are still comfortable, however I do not see them lasting me much longer, which is disappointing.  Shoe was defective. There was a large lump on the ball on foot portion only the insole on the right shoe, a piece of the insole missing from big toe area, and the shoe laces were twisted and messed up. I have returned the shoe and am awaiting a replacement. I did not have adequate time to try them out, but will note that they seemed to fit slightly large.
