Retail price: ¥30,800 I'm selling these because they didn't suit my running style. They have good responsiveness and provide propulsion, so I recommend them for those who want to achieve a personal best. I don't think I've run more than 80km in them. The soles show almost no wear. I ran almost 1000km outdoors in the previous Mach X model, and the soles are still in good condition. I think the X2 will also last a long time. The last two images show the soles of the Mach X after 1000km of use. Please refer to them. They are in good condition, but they are used items. Please refrain from purchasing if you are sensitive to used items. They will be shipped without the box. Thank you.
