Type... Spikes Popular Model/Series... Cloudspike 10000m Color... White ・CloudTec® technology: Lightweight, combining cushioning and responsiveness. ・Carbon fiber Speedboard®: Maximizes propulsion and supports efficient running. ・Highly breathable upper material: Comfortable fit even for long distances. I purchased these, but have only used them once. The previous seller used them once in a 3000m race and about 5-6km in practice. Due to the white color of the shoes, there is some dirt from use. The total running distance is about 10km, so there are no issues with responsiveness. I will ship them in the original box.
