I purchased these here, but they were a little tight, so I'm putting them up for sale. I usually wear 23.5cm, but they felt a bit snug because of a bunion on my right foot, so I'm letting them go while they're still in good condition. I only tried them on indoors. They're light and very comfortable, and I love the design, but I think it would be better if someone who fits the size could use them. The original owner also only wore them once, so they are in beautiful condition.
