ASICS GEL-Cumulus: Key Differences Between the 23 and 24 Models

What is the difference between GEL Cumulus 23 and 24?

The ASICS GEL-Cumulus 24 represents a significant evolution from its predecessor, the GEL-Cumulus 23, primarily through the integration of FF BLAST™ cushioning for a lighter and more energetic ride, alongside a refined GEL™ placement and an updated upper for enhanced comfort and versatility.

Introduction to the ASICS GEL-Cumulus Series

The ASICS GEL-Cumulus series has long been a staple in the running shoe market, known for its reliable cushioning and comfort tailored for neutral runners. Positioned as a daily trainer, the Cumulus aims to provide a soft, protective experience for a variety of runs, from easy recovery jogs to longer training efforts. Each iteration seeks to improve upon its predecessor, often incorporating advancements in material science, biomechanical design, and runner feedback. Understanding the nuances between models, such as the GEL-Cumulus 23 and 24, is crucial for runners seeking the optimal footwear for their specific needs and running style.

Key Differences: GEL-Cumulus 23 vs. GEL-Cumulus 24

The transition from the GEL-Cumulus 23 to the 24 marked a notable shift in ASICS' approach to this workhorse shoe, introducing several key technological and design updates.

• Midsole Technology and Ride

  • GEL-Cumulus 23: This model utilized ASICS' FLYTEFOAM™ cushioning throughout the midsole, complemented by visible GEL™ technology units in both the rearfoot and forefoot. The ride was characterized by its traditional plushness and soft impact absorption, prioritizing comfort over responsiveness.
  • GEL-Cumulus 24: The most significant upgrade. The Cumulus 24 introduced FF BLAST™ cushioning, a lighter and more energetic foam, throughout the midsole. This change provides a more responsive and "bouncier" feel compared to the 23, without sacrificing essential softness. The GEL™ technology was also re-engineered, moving to a more targeted placement under the heel to optimize its cushioning effect during impact. This results in a ride that is not just soft, but also feels more dynamic and efficient.

• Outsole Design and Durability

  • GEL-Cumulus 23: Featured ASICS High Abrasion Rubber (AHARPLUS™) in key high-wear areas, providing reliable traction and durability typical of a daily trainer.
  • GEL-Cumulus 24: Incorporated ASICS LITE™ rubber in the outsole. This material is lighter and more durable than traditional AHARPLUS™, contributing to the overall weight reduction of the shoe while maintaining robust traction and extending the shoe's lifespan. The tread pattern was also subtly refined for improved ground contact.

• Upper Construction and Fit

  • GEL-Cumulus 23: Utilized an engineered mesh upper designed for breathability and a secure, comfortable fit. It offered a traditional, accommodating feel.
  • GEL-Cumulus 24: Featured a new, more adaptive engineered mesh upper. This updated material is softer, more flexible, and designed to provide a more personalized, foot-hugging fit. It also enhanced breathability and reduced the potential for irritation, particularly across the forefoot. The tongue and collar padding were also refined for improved step-in comfort.

• Weight

  • GEL-Cumulus 23: Typically weighed around 10 oz (283g) for men's size 9.
  • GEL-Cumulus 24: Saw a noticeable weight reduction, coming in closer to 9.0 oz (255g) for men's size 9. This lighter profile contributes to the more energetic feel and versatility of the shoe.

• Stack Height and Drop

  • Both models generally maintained a similar heel-to-toe drop (around 8mm) and comparable stack heights, aiming for a balanced cushioning platform that promotes a natural foot strike. The primary differences in underfoot feel stemmed from the foam composition rather than significant geometric changes.

Who is Each Model Best Suited For?

Choosing between the Cumulus 23 and 24 depends largely on individual preferences and running goals.

• GEL-Cumulus 23 Ideal User:

  • Runners who prioritize a traditional, very soft, and plush cushioning experience.
  • Those who appreciate a slightly more structured and accommodating upper fit.
  • Individuals who prefer a ride that focuses purely on impact absorption and comfort, perhaps for recovery runs or lower-intensity efforts.
  • Budget-conscious buyers, as older models often become available at a reduced price.

• GEL-Cumulus 24 Ideal User:

  • Runners seeking a more versatile daily trainer that balances softness with a noticeable level of responsiveness.
  • Those who desire a lighter and more energetic feel underfoot, suitable for a wider range of paces and distances.
  • Individuals who appreciate a more modern, adaptive, and breathable upper fit.
  • Runners looking for the latest ASICS cushioning technology (FF BLAST™) and its associated benefits of improved energy return.

The Evolution of Running Shoe Design

The changes observed between the GEL-Cumulus 23 and 24 are indicative of broader trends in running shoe design. Manufacturers continually strive to:

• Reduce Weight: Lighter shoes often feel faster and less cumbersome over long distances.
• Enhance Energy Return: Newer foam technologies like FF BLAST™ aim to return more of the energy absorbed during impact, making the run feel more efficient and less taxing.
• Improve Comfort and Fit: Advances in engineered mesh and upper construction allow for more adaptive, breathable, and irritation-free fits.
• Optimize Cushioning Placement: Strategic placement of cushioning elements (like GEL™) can maximize their effectiveness without adding unnecessary bulk.

This iterative process ensures that each new model brings tangible improvements, catering to the evolving demands and preferences of the running community.

Conclusion and Recommendation

While the ASICS GEL-Cumulus 23 was a reliable and comfortable daily trainer, the GEL-Cumulus 24 represents a significant upgrade, offering a more dynamic, lighter, and versatile experience thanks to the introduction of FF BLAST™ cushioning and other refinements.

For runners seeking a more modern, energetic, and adaptable daily training shoe, the GEL-Cumulus 24 is the clear choice. However, those who prioritize the traditional, exceptionally plush, and purely soft ride of the Cumulus series might still find the 23 appealing, especially if available at a competitive price. Ultimately, the best way to determine the ideal shoe is to try both on, ideally at a specialized running store, and assess which feel aligns best with your unique biomechanics and running preferences.
