I wore the Blue ones ALL night, and they were super stable and comfortable. I could feel them forming to my feet as the night went along. They were very stable, and felt more like dancing in flats than heels. My feet felt fine at the end of the night and no blisters. I like the heel placement and never felt I was being pushed off balance.
They fit right out of the box, even with my busted up left foot. I'm in love.
Up to this point I was very cautious when it comes to heels. Even if they were supposed to be comfy, after few dances I wanted to throw them away together with my hurting feet. First contact with Hepcats was a pleasent surprise (wow, soft and comfy) but after a few hours of dancing I really felt the difference. I remembered that I have them on only beacuse I couldn't stop looking at them!
