"I bought this first pair and everything was perfect. Your feet don't slide forward, actually extremely comfortable and stylish. Then after about 2 weeks, I noticed the peeling of the thin rubber part from the shoe. I superglued it thinking it should be okay. It was fine.
Since I loved these so much, I bought them in black. They arrived and I didn't try them on as I had purchased the same size. I took them on a business trip only to find they fit at least a 1/2 size too small - length wise and almost fitting like a narrow shoe. Completely disappointed and very painful to wear all day. I didn't return them to the store since I had worn them. If I can provide any warning . . . seems like a quality control issue on both pairs I purchased. Buy with caution. I am a solid 8.5M."
