When these shoes arrived I had high expectations for them. Firstly they arrived smelling very chemically, and they looked like they had been worn before. I thought I would try them anyway. I wear a size 9 C/D or W. I purchased the 42. They were tight over the tops of my feet, but fit in the width and length. Had I gone a size bigger, they would have been too long.
They were not just snug, but tight, So tight that in the short time I wore them my feet went numb. It's been a few weeks since I returned them and I still have numbness on the top of my left foot.
I don't recommend these shoes for wide feet, as they fit in the width, but not across the tops of feet.
