Purchased in January 2025. I am selling these as I haven't had many opportunities to wear them. I only tried them on, and haven't worn them outside. They are made of a soft material that is unlikely to cause blisters. I also have them in silver, so please check if you are interested. Color: Silver Size: 24.5 Heel Height: 0.5 The upper is made of only soft material! These flat pumps are made with a focus on comfortable wear. They have a sleek silhouette, yet are comfortable to wear without feeling constricted, making them a great addition to your everyday adult wardrobe.
