On CloudSpike Citius

Ignite the track with the On CloudSpike Citius mid distance track running spikes, part of the exclusive Prism Capsule Collection that enhances your race day performance with exceptional speed and flair.

These limited edition track spikes stand out with their vibrant colourway, representing the ambition and unity in the world of running. Developed, tested and approved by elite On track runners, they provide a winning formula of aggressiveness and energy return.

BIG ENERGY RETURN
A stiff Speedboard at the forefoot disperses force and amplifies energy return, which results in powerful take-offs. And a fine-tuned Helion™ HF hyper foam midsole converts this stored energy into potent propulsion.
STRATEGIC SUPPORT
Designed with race day performance and speed in mind. Its ultralight, one-piece, mesh upper helps to reduce overheating. And its cage-like construction locks down the foot for a supportive, race-ready fit.
ATHLETE APPROVED
Designed and tested by On's top track runners, the Cloudspike Citius exceeds the high demands of middle distance athletes with an optimized forefoot stack height (23mm) to achieve the perfect balance between energy return and aggressiveness.
