Thank you for viewing. I am selling a pair of Inx Break spikes that I purchased about 4 years ago. I have used them twice for training. The upper is the same as the Chrono Inx, with a skeleton upper. It is designed for lightweight performance. The sole is the same as the Chrono Break, providing greater stability for straight-line running. It has one less spike than the Inx. Compared to the Inx, I felt it was slightly more prone to lateral movement upon ground contact. They are lightweight and have great responsiveness, making it very easy to run and accelerate smoothly. Color: Red/White Size: 25.0cm Please ask any questions in the comments.
