Sole
The Cloudspike Citius 2 features a modern midsole made of ultra-soft Helion™ HyperFoam, made from Pebax®. This high-performance foam provides excellent cushioning and a high level of energy return, keeping you running at speed. The foam is combined with the unique CloudTec® technology. CloudTec® are the "clouds" that absorb both horizontal and vertical shocks, making your landing extra soft. Once your feet touch the ground, the clouds stay firmly in place, allowing you to push off with a powerful push. The unique full-length Speedboard® is a blend of fiberglass and nylon that boosts your speed and helps you propel forward. The outsole features six removable spikes and a heel cushion with grippy surfaces.
Upper
The Swiss-Engineered mesh upper provides flexibility and breathability in strategic areas, while the shoe fits a little tighter in other areas. The shoe is slightly tighter around the midfoot for a secure and supportive feel. The upper is also made of recycled materials. This is one of the ways On is constantly striving to make its products more sustainable. The Cloudspike Citius 2 offers incredible grip during your matches thanks to the combination of a synthetic outsole and spike plate. The synthetic outsole features extra texture to guarantee extra grip. Get the On Cloudspike Citius 2 now and improve your performance on the court, delivered to your home within a few days!
