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.

Foxxy Black Heel
Size: 6.5, Color: Black Patent
10/10 recommend. I love Steve Madden shoes. These were actually comfortable. I love the style and quality. The height was perfect for me. I was turning heads. The gold buckle and solid black made the heel pop!

Heel girly
Size: 8, Color: Burgundy Patent, Size: 8, Color: Burgundy Patent
The bottom is very slippery and you need cushions to go at the bottom of them. You have to be a real heel girly to walk in them, slightly comfortable.
