Thank you for viewing. These are On Cloud All Black, size 27.5 cm. I purchased them and wore them a few times, but they didn't quite fit my feet, so I'm selling them. They are in good condition and ready to wear. They will be packed in the original box and shipped. The following is an excerpt from the product page: Developed to achieve a soft landing and explosive push-off, On's patented CloudTec(R) technology. As a result, we have succeeded in providing an incredibly light running sensation. We have made no compromises on cushioning and impact protection, achieving a feeling like running on clouds. Be active every day with Cloud. Always, On. Never Not On Retail price: ¥15,180
