An Elite Long-Distance Spike Built to Propel You Towards Your Track Season Goals

With the Cloudspike Amplius 2, On Running has released a speedy long-distance track spike meant to help you achieve a PR during your next track and field season. Now on the second iteration of the shoe, this high-performance spike balances comfort with energy return for athletes in distance events up to the 10,000 meters.

The Cloudspike Amplius 2’s midsole is composed of Helion HF foam, an ultra-responsive cushioning that provides maximum energy return without sacrificing comfort and shock absorption. The midfoot nylon-blend speedboards add even more energy return and propulsion while also providing extra arch support and stability throughout the longest track events.

Underneath the shoe, the five spike pins optimize traction for exceptional grip when you take to the track for your race. Last but certainly not least, the upper uses a one-piece polyester design to comfortably wrap the foot without adding any additional weight. If you’re looking for a speedy and lightweight distance spike to help you reach your goals next season, this light and efficient Cloudspike Amplius 2 might be the perfect choice for you.
