Cute but at what cost.
Size: 7.5, Color: Champagne
This is probably now the cutest pair of heels I own. But they are not comfortable by any means.

Chic and surprisingly comfortable
Size: 7.5, Color: Champagne
These sandals are gorgeous! The style is sleek and elegant, perfect for both casual and dressy outfits. I was worried they might be uncomfortable, but they’re easier to walk in than I expected and don’t hurt my feet after wearing them for hours. The quality feels great and they definitely look more expensive than they are. Highly recommend if you want a stylish heel that you can actually wear.

Very uncomfortable
Size: 7, Color: Brown Patent
Most uncomfortable shoes I own. The middle part is so hard and digs into your toes making it really painful. I wear a lot of heels and never have I had a pair that hurt this bad.
