Stylish and comfy
I am very pleased with these shoes! I got lots of compliments and interest at a recent wedding I wore them to. I was able to dance and walk around for most of the night comfortably. One of a kind!

Love these, but you may want to size up.
And didn’t stumble in them at all :). Great looking and fairly comfortable for a high heel, and took me through the night. I did size up from a 40 to a 41 and the fit was perfect, as the sole is a little narrower. I will be totally honest that I had to change towards the end, but lasted a solid 5 hours.
