Thank you for viewing. This is a listing for On's latest speed model, the "Cloudflow 5". [Usage Status] • Mileage: Used only twice, for a total of 30km. • Usage Location: Both times were used only on "tartan (athletic track)". They have never been run on asphalt, so the outsole wear is extremely minimal and the cushioning is in very good condition. • Reason for Listing: These are excellent shoes perfect for training in the 3-minute per kilometer range, but they did not fit my foot shape, so I have decided to sell them while they are still in good condition. [⚠️ Note on Accessories] • Outer Box: The original outer box has been discarded and will not be included. They will be carefully packed in a different box or with cushioning material for shipping. • Insoles: Both the high-performance **BMZ "Cuboid Balance"** insoles (currently installed) and the unused original insoles will be included. [⚠️ Regarding Price] • We sincerely apologize, but we kindly ask that you refrain from price negotiations. Please consider the current price. [Product Features] • Speed Performance: Extremely lightweight and ideal for interval runs and tempo runs. • BMZ Insoles: The structure supports the cuboid bone, promoting stable ground contact and powerful push-offs. [Product Details] • Brand: On • Model: Cloudflow 5 • Size: 26.5cm • Shipping Method: No box (will be carefully packed) How about using them for your track interval training? Please only purchase if you understand that these are used items.
