These are Asics racing shoes. They are the model commonly known as "Skasen." I owned three pairs in total, but I'm selling them because I don't use them anymore. I've run two half marathons and one 30km run in them, so please judge the condition from the photos. Although there is some dirt on the soles, I think the overall condition is clean. The fit is snug. As racing shoes, they are generally made small. In this era of thick-soled shoes, I believe these types of shoes are important for training and strengthening landing muscles. Isn't the asymmetrical design still fresh even now? I am also selling Tartherzeal 6. Please contact me if you are interested in purchasing them together!
