At 157g, it slots between pure sprint spikes and heavier distance trainers, featuring On’s Helion HF hyper foam midsole that promises to keep your legs fresh through those punishing final laps. The 7mm drop and neutral cushioning create a balanced platform that won’t force you into an unnatural stride when fatigue sets in. What sets the Amplius 2 apart from typical track spikes is its focus on cushioning without sacrificing ground feel. The CloudTec pods compress on impact but maintain enough structure for efficient toe-off, while the rigid spike plate ensures every watt of power transfers to the track. It’s designed for runners who need more protection than a minimal spike but can’t afford the energy drain of overbuilt cushioning. Whether you’re chasing PBs in the 5K or grinding through 25 laps, this spike aims to balance comfort and speed across the distance spectrum. Who It’s For Middle and long-distance track athletes (1500m-10K) who want more cushioning than traditional minimal spikes without sacrificing responsiveness Collegiate and club runners transitioning from road racing to track events who need a spike that won’t punish their feet over multiple heats Masters athletes looking for a performance spike with enough protection to handle the repetitive impact of oval running Who Should Skip It Sprint specialists (100m-400m) who need maximum power transfer and minimal weight — the Nike Air Zoom Maxfly 2 offers a more aggressive platform for pure speed Steeplechase runners requiring drainage and water clearance — consider the Nike ZoomX Dragonfly XC which handles water barriers better Budget-conscious athletes who can’t justify the $225 price point — the Nike Zoom Superfly Elite 2 delivers solid performance at $179.99 Key Specs Weight 157.3g Drop 7mm Spike Configuration 5 removable pins Midsole Helion HF Hyper Foam Cushioning CloudTec pods How It Compares Model Weight Drop Best For Price On Cloudspike Amplius 2 157g 7mm 3K-10K track $225.00 Nike Air Zoom Maxfly 2 155g 5mm 100m-400m sprints $280.00 Nike Zoom Superfly Elite 2 135g 4mm 800m-1500m $179.99 The Tech That Matters The Helion HF (Hyper Foam) midsole represents On’s latest advancement in track-specific cushioning. Unlike the standard Helion used in their road shoes, the HF variant prioritises energy return over durability — you’re trading longevity for performance, which makes sense given track spikes typically see far fewer kilometres than trainers. The foam delivers a snappy, responsive feel that doesn’t bottom out during longer efforts, crucial when you’re 20 laps into a 10K and still need pop off the track. On’s CloudTec pods function differently in a spike than in their road shoes. Here, they’re compressed into a lower profile that still provides impact protection without the pronounced “rolling” sensation of their thicker trainers. The pods work in conjunction with the spike plate to create distinct pressure zones — softer under the heel for those who still heel-strike at distance pace, firmer through the midfoot for stability, and rigid at the forefoot where the spike pins deliver traction. Real-World Performance The 7mm drop strikes a middle ground that accommodates various running styles. It’s low enough to encourage a midfoot strike without forcing it, which matters when form deteriorates in the final kilometres of a 10K. The neutral cushioning doesn’t try to correct your gait, letting you run naturally while the spike plate provides the structure needed for efficient propulsion. At 157g, the Amplius 2 sits in the sweet spot for distance track events. It’s light enough that you won’t feel anchored to the track, but substantial enough to provide genuine cushioning over 25 laps. The removable 5-pin configuration allows customisation based on track conditions — you might run all five for a wet track or remove the heel pins for dry conditions where you’re primarily on your forefoot. Design and Fit On has focused on creating a spike that disappears on your foot during longer efforts. The upper uses lightweight mesh that provides structure without bulk, essential when every gram counts but you still need your foot locked in place through thousands of strides. The fit runs true to size with a snug midfoot that opens up slightly in the toe box — enough room for natural splay during toe-off without feeling sloppy. The spike plate extends from heel to forefoot, providing a stable platform that doesn’t twist under lateral forces. This matters more than you’d think in distance events where fatigue can lead to inefficient foot strikes and wasted energy. The plate’s rigidity increases progressively toward the forefoot, matching the natural flex pattern of your foot during the running gait. Durability Concerns Let’s be honest about the trade-offs. The Helion HF foam prioritises performance over longevity — expect 300-400km of track use before the midsole starts losing its pop, less if you’re heavier or run with a particularly aggressive foot strike. The CloudTec pods show wear patterns quickly, though this is mostly cosmetic and doesn’t affect performance until deep into the shoe’s life cycle. The upper materials are appropriately lightweight, which means they won’t handle abuse like a daily trainer. Keep these for races and quality sessions, not warm-up jogs on concrete. The outsole rubber is minimal by design — just enough for traction between the spike pins, so don’t expect these to transition well to road running. Price Intelligence Currently available at Pace Athletic for $225.00, down from the regular $250.00 retail price — that’s a 10% discount on a current-season spike. This pricing positions the Amplius 2 in the premium segment but below elite sprint spikes. Given On’s typically stable pricing and the fact this is a specialised product with limited retail distribution, grabbing it at any discount is worthwhile if you’re in the market. Value Rating �������� (4/5) At $225 (discounted from $250), the Cloudspike Amplius 2 delivers genuine innovation in the distance spike category. The Helion HF foam and CloudTec system offer tangible benefits for longer track events, justifying the premium over basic spikes. You’re paying for Swiss engineering and comfort features rarely found in track spikes. Loses a point because the durability doesn’t match the price — this is a performance tool, not a workhorse. The Bottom Line The On Cloudspike Amplius 2 fills a specific niche: distance track runners who want more cushioning than traditional minimal spikes provide but can’t sacrifice the responsiveness needed for fast times. It’s particularly well-suited to runners stepping up from 1500m to 5K/10K events who need extra protection for the increased volume, or masters athletes who prioritise joint protection alongside performance. The combination of Helion HF foam, CloudTec pods, and a 7mm drop creates a platform that maintains comfort through long track efforts without feeling disconnected from the surface. Yes, you’re paying premium prices for Swiss engineering, but if you’re serious about middle and long-distance track running and want every advantage in those final laps, the Amplius 2 delivers where it counts.
