Thank you for viewing. I am selling spikes that I purchased about four years ago. I have used them 1-2 times. They use the same upper as the Chronobrake, so they fit well with the foot and there is no slippage inside the spike. The sole is the same as the Geo Sprint, and the forefoot uses a hard plate, allowing for immediate repulsion, which enables smooth speed-up during acceleration. These two features are mixed, making it a spike model specialized for short distances. The purchase price was just under 30,000 yen. Color: Red/Black/Gold Size: 25.0cm Please ask any questions in the comments.
