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.

Poor Quality for the Cost !!! Dissatisfied
Disappointed Durability. I love these heels they are very comfortable looks good with just about any color outfit . However, my heart ripped in pieces after 3 months with limited wear they began to lift and fall apart . I’m very dissatisfied with the cost & poor quality slippers I received. I wish I could actually returned it but couldn’t due to the 30 days return policy.

Steve Madden must have
Size: 7.5, Color: Black
You can’t go wrong with any Steve Madden shoe to be honest. These are sexy yet sturdy. Nice thin versatile heel. Strap length is good for any size ankle really
