Built specifically for 800m to 1500m racing, this spike maximises the allowable 20mm stack height with 100% Helion HF superfoam — On’s lightest, most responsive compound. The Swiss brand has essentially reverse-engineered the regulations, packing as much explosive foam as legally permitted into a 156g package. The engineering philosophy here differs markedly from traditional spike construction. Rather than minimal cushioning with a rigid plate, On has opted for a foam-forward approach that prioritises energy return through the midsole. The recycled polyester mesh upper strips away unnecessary structure, functioning more as a lightweight cage than a traditional shoe upper. At $162.50 from Pace Athletic (down from $250), you’re looking at serious middle-distance hardware that’s currently 35% off its launch price. Who It’s For 800m-1500m specialists seeking maximum legal cushioning — The 20mm stack of Helion HF delivers more impact protection than traditional spikes while maintaining explosive toe-off through the integrated spike plate Runners prioritising propulsion over pure minimalism — The 7mm drop and forward-rolling geometry suit athletes who generate speed through powerful push-offs rather than high cadence Track athletes above 65kg who need cushioning without sacrificing speed — The Helion HF maintains energy return across a wider weight range than traditional minimal spikes Who Should Skip It Sprinters running 400m or shorter — The cushioning-focused design sacrifices the immediate ground contact sprinters need. Consider the Nike Air Zoom Maxfly 2 for pure speed events Runners who prefer minimal, ground-feel spikes — The 20mm stack height prioritises cushioning over track feel. The Nike Zoom Superfly Elite 2 offers a more traditional spike experience Cross-country or varied surface runners — The track-specific spike plate won’t handle off-track surfaces. Look at the Nike ZoomX Dragonfly XC for versatility Key Specs Weight 156g Stack Height 20mm (World Athletics maximum) Drop 7mm Midsole 100% Helion HF superfoam Upper 100% recycled polyester mesh Target Distance 800m – 1500m Gait Type Neutral Technical Breakdown The Citius 2’s defining feature is its maximalist approach to spike design within regulatory constraints. The 20mm Helion HF midsole represents On’s lightest foam compound, engineered specifically for explosive energy return rather than durability. This isn’t a training spike — every element targets race-day performance. The spike plate configuration focuses on forward propulsion through the forefoot, with pin placement optimised for the power phase of middle-distance running. The 7mm drop encourages a midfoot strike pattern typical of 800m-1500m pacing, where runners balance speed with efficiency over multiple laps. Upper construction takes minimalism seriously. The recycled polyester mesh functions as a containment system rather than a support structure, with strategic ventilation zones positioned based on heat mapping data from middle-distance efforts. The cage-like design locks the foot during cornering without adding unnecessary material. How It Compares Model Weight Stack Height Best For Price On Cloudspike Citius 2 156g 20mm 800m-1500m $162.50 Nike Air Zoom Maxfly 2 160g Not specified 100m-400m $280.00 Nike Zoom Superfly Elite 2 135g Not specified 100m-200m $179.99 Real-World Performance The Citius 2 occupies an interesting position in the spike market — maximum cushioning within legal limits. This approach particularly benefits runners transitioning from road racing to track, where the additional cushioning eases the impact forces of repeated track laps. The Helion HF foam maintains its energy return properties across temperature ranges typical of Australian track conditions. Unlike some super foams that stiffen in cold weather, the compound remains consistent whether you’re racing evening twilight meets in Melbourne or afternoon competitions in Brisbane. Durability expectations should align with the spike’s purpose. This is competition-specific footwear, not a daily track trainer. The aggressive spike plate and lightweight upper construction prioritise race performance over longevity. Budget for 15-20 race efforts before noticeable performance degradation. Price Intelligence Currently available at $162.50 from Pace Athletic, representing a significant 35% discount from the $250 RRP. This pricing positions the Citius 2 competitively against other premium middle-distance spikes, especially considering the advanced foam technology and World Athletics-compliant design. The current discount likely reflects end-of-season inventory management rather than any product issues. Track spike pricing typically fluctuates with the athletics calendar — expect prices to firm up as the summer track season approaches. If you’re planning for upcoming competitions, the current pricing represents genuine value. Value Rating (4/5) At $162.50, the Citius 2 delivers premium spike technology at mid-tier pricing. You’re getting On’s most advanced foam compound, a purpose-built spike plate, and race-ready construction for less than many competitors. The only value consideration is durability — these are pure racing spikes, not versatile trainers. Factor in the limited lifespan when calculating cost-per-wear.
