Gorgeous
Size: 9, Color: Tan
These are so pretty! I ended up returning these because they were so tall and I couldn’t walk in them as good as I thought I was going to be able to. Besides that, they fit true to size and were comfortable.

Wouldn’t recommend these sandals.
I was really excited to try the Steve Madden Women's Wafer Heeled Sandals, but unfortunately, I’m disappointed with the quality. The sandals look great in photos, but when I received them, I noticed that the materials felt cheap and not as durable as I expected from a brand like Steve Madden. The straps are stiff, and they rubbed against my skin, causing discomfort after only a short amount of time.
The fit also wasn’t great — they felt a bit tight, especially around the toes, which made them hard to wear for longer periods. While the heel height is cute, the overall construction doesn’t seem to provide enough support, which made walking in them less comfortable than I anticipated.
For the price, I expected better quality and comfort. Unfortunately, I wouldn’t recommend these sandals.

Perfect black patent leather heel
Size: 6.5, Color: Black Patent
Definitely go up an entire size in these. I used to work at Steve Madden and can tell you with 100% confidence if you're ever buying one of their heels with a pointier toe, you need to go up an entire size or your foot is going to suffer. These are a perfect "high" stiletto, they're definitely not low and I wouldn't say they're a breeze to walk in unless you're used to heels. I will vouch for how comfortable they are though given the height and the shape - they're as comfortable as a heel like this could be for sure! If you have skinnier ankles, definitely recommend punching an extra hole in the strap.

toe strap is tewww tight
Size: 8, Color: Black
I love the look of these heels, they’re super classy, elegant, simple, and most importantly I chose these because of the small platform at the base of the heel for a less painful experience. The onlyyyyyy issue I have is that the toe strap is so close to the front and tight (as you can see)!! I got the correct size but wish I didn’t have to stretch them out (which is almost impossible because that leather is stiff). The shoe is not very bendable but I personally like it because the shoe is sturdy.
