I am size 11.5-12, depending on the brand of shoe. These were recommended to me, and I purchased them on Amazon for around $60. I tried them for a full two days at work and decided I do not like the fit. I have flatter feet, and these just don't feel right for me. They are like new in the original box. I am throwing in another pair I received as a gift. Same story, barely worn. Just didn't like how they felt. $40 take them both.
