On Cloudswift Running Shoes: Key Differences Between Cloudswift 2 and 3

What is the difference between Cloudswift 2 and 3?

The On Cloudswift 3 represents a significant evolution from its predecessor, the Cloudswift 2, primarily through the introduction of CloudTec Phase® technology for a smoother ride, an updated Helion™ superfoam for enhanced cushioning, and a refined upper design for improved comfort and fit, collectively offering a more integrated and responsive urban running experience.

Understanding the On Cloudswift Series

The On Cloudswift series is engineered specifically for urban running, designed to provide a balance of cushioning, responsiveness, and protection on hard surfaces. It targets runners who navigate cityscapes, demanding a shoe that can absorb impact from concrete and asphalt while offering a nimble feel for varying paces and quick turns. Both the Cloudswift 2 and Cloudswift 3 aim to deliver this experience, but the latter introduces key innovations to refine it.

Key Innovations in the Cloudswift 3

The Cloudswift 3 is not merely an incremental update; it incorporates several distinct technological advancements that fundamentally alter its performance characteristics compared to the Cloudswift 2.

• CloudTec Phase® Technology: This is the most significant upgrade. Unlike the more traditional, distinct Cloud elements found in the Cloudswift 2, CloudTec Phase® features interconnected, collapsing Cloud elements that are designed to work in sequence. This patented technology enables a smoother, more seamless transition from heel strike to toe-off, creating a gentle rolling sensation that mimics the foot's natural motion. The result is a less "segmented" feel and a more fluid ride.
• Updated Helion™ Superfoam: While both models utilize On's proprietary Helion™ superfoam, the Cloudswift 3 features a re-engineered density and composition. This update aims to provide an even softer landing without sacrificing energy return, leading to a more cushioned yet still responsive ride. The foam works in conjunction with the new CloudTec Phase® to optimize impact absorption and propulsion.
• Refined Upper Construction: The Cloudswift 3 boasts a redesigned engineered mesh upper. This update focuses on improving the overall fit, breathability, and lockdown. It often features a more adaptive stretch and strategic zones of support, providing a more comfortable and secure wrap around the foot compared to the Cloudswift 2's upper.

Core Differences: Cloudswift 2 vs. Cloudswift 3

A direct comparison highlights how these innovations translate into tangible differences in feel and performance.

• Midsole and Cushioning:
  • Cloudswift 2: Utilizes individual Cloud elements and Helion foam. Offers good cushioning, but the distinct pods can sometimes be felt more prominently underfoot, especially on specific foot strikes.
  • Cloudswift 3: Incorporates CloudTec Phase® and an updated Helion foam. Provides a noticeably softer and more integrated cushioning experience. The sequential collapse of the Clouds reduces the "pod" sensation, creating a more uniform feeling of plushness.
• Ride and Transition:
  • Cloudswift 2: Delivers a responsive ride with a decent transition, but the individual Cloud elements can lead to a slightly less fluid roll-through.
  • Cloudswift 3: Engineered for a significantly smoother and more seamless ride. The CloudTec Phase® system promotes a fluid, rolling motion from landing to push-off, enhancing the efficiency and comfort of each stride.
• Upper Fit and Comfort:
  • Cloudswift 2: Features an engineered mesh upper that provides a comfortable and secure fit.
  • Cloudswift 3: The refined upper offers an even more adaptive and accommodating fit, often feeling softer against the foot with improved breathability and a more secure midfoot lockdown, reducing any potential for slippage.
• Outsole Durability and Grip:
  • Both models utilize durable rubber compounds strategically placed for traction. The Cloudswift 3 may feature minor refinements in outsole pattern to complement the new midsole geometry, but fundamental grip performance remains high for urban environments.
• Weight: While both are relatively lightweight for their cushioning level, minor weight adjustments may occur between iterations due to material and design changes. These are typically negligible in real-world performance.

Intended Use and Runner Profile

Both Cloudswift models excel as daily trainers for urban environments, but the improvements in the Cloudswift 3 broaden its appeal.

• Cloudswift 2: Ideal for daily training, shorter to medium-distance runs, and general urban activity. It serves runners looking for a responsive yet cushioned ride on hard surfaces.
• Cloudswift 3: Caters to the same urban runner but offers enhanced comfort and a smoother ride, making it suitable for longer runs and higher mileage. Its integrated feel also makes it appealing for those who prefer a less "structured" sensation underfoot while still benefiting from ample cushioning and energy return. It's an excellent choice for runners seeking a versatile daily trainer that can handle varied paces with enhanced comfort.

Making Your Choice: Cloudswift 2 or 3?

When deciding between the Cloudswift 2 and Cloudswift 3, consider the following:

• Ride Preference: If you prioritize a distinctly smooth, rolling sensation and an integrated cushioning feel, the Cloudswift 3 with its CloudTec Phase® is the superior choice. If you don't mind a slightly more traditional "podded" feel and can find the Cloudswift 2 at a reduced price, it remains a capable shoe.
• Cushioning Softness: The Cloudswift 3 generally offers a softer initial step-in feel and a more cushioned overall experience due to the updated Helion foam and CloudTec Phase® system.
• Fit and Comfort: The refined upper of the Cloudswift 3 typically provides a more comfortable and adaptive fit for a wider range of foot shapes.
• Budget: As the newer model, the Cloudswift 3 will likely be at a higher price point. If budget is a primary concern, the Cloudswift 2, if still available, could offer good value for its performance.

Ultimately, the best way to determine your preference is to test run both models if possible. The subtle nuances in feel and fit can significantly impact your running experience.

Conclusion

The On Cloudswift 3 represents a significant refinement and technological leap over the Cloudswift 2. While the Cloudswift 2 established the series' reputation as a reliable urban trainer, the Cloudswift 3 elevates the experience with its innovative CloudTec Phase® technology, updated Helion™ superfoam, and improved upper. These enhancements result in a distinctly smoother, more integrated, and more cushioned ride, making the Cloudswift 3 a highly capable and comfortable option for urban runners seeking a premium daily training shoe.
