- Brand: On - Color: Black - Model Name: Cloudmonster 1 This is the first Cloudmonster model by On. I bought these for running and everyday wear, but they don't fit, so I'm selling them. I've used them for about 80km, including running. The soles aren't very worn, but the heels are slightly torn. I purchased them from the official Amazon store. Since there are many fakes out there, I can take detailed photos if you'd like, so please feel free to comment. The following is quoted from the website: Weight: 275g Road running shoes that offer maximum cushioning and an incredible rebound feel. Comfortable fit provided by the soft insole and upper. High energy return generated by the highly responsive Speedboard®. Monster-specific rocker shape that creates efficient propulsion. Helion® super foam absorbs impact upon landing. Lightweight yet durable and temperature resistant.
