Full review

The On Cloudnova X 3 stands as one of the most versatile entries in On Running's celebrated lineup, engineered specifically for athletes who demand performance across multiple training disciplines. This training shoe merges the brand's signature CloudTec cushioning technology with a streamlined, low-profile design that supports everything from high-intensity interval training to short-distance running and gym-based workouts. The shoe's structure reflects On's ongoing refinement of its franchise, delivering a shoe that feels lighter and more responsive than earlier iterations while maintaining the brand's commitment to durable, functional athletic footwear.

At the core of the Cloud X 3 is a dual-density midsole that balances soft landing cushioning with a firmer, more stable base for lateral movements and explosive push-offs. The iconic Cloud elements along the outsole compress upon impact and then engage the Speedboard, a thin embedded plate that runs through the midsole to generate a springy, energized toe-off. This combination makes the shoe particularly well-suited for circuit training, plyometric exercises, and agility drills where quick direction changes and repeated ground contact are constant demands. The engineered mesh upper wraps the foot securely while remaining breathable, and a supportive heel counter locks the foot in place during lateral cuts and rapid stops, reducing slippage during dynamic movement.

Designed with the modern fitness enthusiast in mind, the Cloud X 3 also emphasizes everyday wearability, with a sleek silhouette that transitions easily from the gym to casual wear. The shoe's weight has been trimmed down compared to previous models, contributing to a nimble, low-to-the-ground feel that many cross-trainers and functional fitness athletes appreciate. Reinforced overlays add structural integrity in high-wear zones, while the rubber outsole pattern is optimized for grip across varied surfaces, from studio floors to outdoor pavement. Available in a range of colorways, the Cloud X 3 continues On's tradition of pairing Swiss engineering with athletic function, offering a dependable training companion for those who refuse to compromise between comfort, support, and performance.

Perfect for my CrossFit workouts

I've been using the Cloud X 3 for three months now doing CrossFit and HIIT training. The stability during box jumps and burpees is fantastic, and my feet don't feel fatigued even after long sessions.

MT Marcus T.2024-02-28 ★★★★★
Great all-rounder, slightly snug fit

Solid shoe for gym work and occasional 5k runs. The cushioning strikes a nice balance between responsive and comfortable. Only downside is the toe box feels a bit tight if you have wider feet like me.

PK Priya K.2024-01-10 ★★★★★
Durable and stylish

After six months of regular use in spin class and weight training, the outsole still looks great. Breathability is excellent even during sweaty sessions. Wish it came in more color options though.

DR David R.2023-12-05 ★★★★★
Best training shoe I've owned

Switched from running shoes to these for my gym routine and the difference is night and day. The lateral stability is exactly what I needed for agility drills and the Helion foam feels amazing underfoot.
