On Running Cloudspike Amplius 2 Women's Running Spikes

Pinnacle track spikes for races up to 10,000m. Athlete informed track-specific geometry, with a CloudTec cushioning system engineered for fast runs.

Zoned Woven Upper

Engineered with a lightweight, breathable one-piece upper, the Cloudspike Amplius 2 is built for dominating the track. Designed with race day performance and comfort in mind, the featherweight upper provides a supportive feel for peak performance. Light in weight and with a one-piece design, chafing and irritation are eliminated, and there is no bulk to hold you back. A standard lacing system allows you to lock in the fit, minimising in-shoe slippage to keep you feeling secure and stable as you fly along.

Advanced Midsole and Outsole

The midsole utilises highly responsive Swiss-engineered Helion HF hyper foam, supplying advanced energy return to reduce impact on the body and prevent injury. The responsive and supportive cushioning adapts to your running style, allowing you to really let loose and keep your legs feeling fresh till the very end. The Cloudspike Amplius 2 also features a Nylon-blend Speedboard for midfoot stability and arch support, enabling athletes to maintain an efficient and steady pace on longer runs. With a legal stack height of under 20mm, this spike is perfect for all your long-distance competitions and track events. Finally, the spikes feature five lightweight spikes alongside precise traction optimisation to provide you with unmatched grip on the track, helping you leave the others in the dust.
