I bought these but they've become too small without me ever wearing them. They are new and unused, but there is a faint yellow stain, possibly paint, on the side of the shoe. I don't think it will affect wear. The heel of one shoe lights up. The other one doesn't light up, possibly because the battery is dead. As a bonus, I'm including a pair of 16cm indoor shoes. They are in near-new condition. I plan to ship them in simple packaging. Discounts are available if you purchase them with other items! Due to shipping costs, I will pack them compactly for shipping.
