I bought these in black and office nude. I didn't notice any manufactural defect out of the box like many others did and they did arrive very quickly but I have to admit, half way through the day my feet were in so much pain that I had to take them off. I wear heels regularly but these chaffed against the inside and outside of my foot and I had huge, painful, red blisters by lunchtime. I do have somewhat wider feet and I was on my feet almost all morning so these could be factors, just wearer beware. I won't be returning them because they are so cute but I will make sure I only wear them when Ill be sitting down a lot through the day.
