you're right....they do look potentially uncomfortable. I like them, but I'm not sure about the heel shape. They're a good choice if you're looking for something gold to wear with pants that are a bit too short for a higher heel.
I don't know if they'll hurt or not but they're definitely cute!
I have some black ones that are very similar except in suede and I wear them 2 or 3 times a week. I didn't think I would but they're so comfy and cute that they always seem to be my choice in the mornings for work!
