These white and yellow running shoes, known for their excellent cushioning, were sold as a limited edition item in limited quantities. They are built like the Cloud, with an upper design that pays homage to triathlon shoes, making them suitable for everyday wear. I have only used them for casual wear, so there is almost no wear and tear on the heels. - Brand: On - Color: White/Yellow - Style: Running Shoes - Sole Type: Cushioned Sole Thank you for looking.
