On Cloudspike Amplius 2 Women's Running Spikes

Your long-distance track spikes. A perfect combination of cushioning and energy return for races up to 10,000m.

Lightweight One-Piece 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 keeping 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. The Cloudspike Amplius 2 also features a Nylon-blend Speedboard for midfoot stability and snappy propulsion for even more energy return and an explosive toe-off, as well as encouraging a more natural stride. 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 a surface-gripping heel pad to provide you with unmatched traction on the track, helping you leave the others in the dust.
