The On Cloudspike Amplius 2 is a long-distance track spike built for races from 3,000m to 10,000m. A Helion HF superfoam midsole brings the cushioning and energy return you'd expect from On's road shoes, and a top-loaded Speedboard adds midfoot stability and a strong kick off the final bend.
The recycled polyester upper is breathable and light, and the Pebax spike plate uses five pins to save weight while keeping grip. It's a roomy, forgiving spike for 5000m and 10,000m racing. Neutral.
