Which ASICS Running Shoes Should You Buy? A Guide to Their Best Models
ASICS makes some of the most reliable running shoes on the market, particularly if you prioritise cushioning and impact protection over minimalist designs. The current range includes two standout options: the Gel-Nimbus 27 (£80) for maximum comfort and the Megablast (£225) for responsive performance. Your choice depends on whether you're training for distance or chasing pace.
Why ASICS?
ASICS (Asahi Rubber Industries, founded 1949 in Japan) specialises in sports footwear engineered for impact absorption. Their signature Gel cushioning technology—silicone-based shock absorption built into the midsole—remains their defining feature after decades of refinement. Unlike minimalist competitors, ASICS prioritises joint protection and stability, making them particularly popular with distance runners and those with pronation concerns. They also invest heavily in biomechanical research; most models go through extended testing in their laboratories before release.
Top Picks
ASICS Gel-Nimbus 27 — £80
Best for runners prioritising maximum cushioning and comfort over speed. This is the standout value pick in the current range. The Gel-Nimbus 27 combines ASICS's traditional Gel cushioning system with FlyteFoam technology (a lighter, more responsive foam core), delivering a plush ride without the bulk of older models. At £80, it's significantly discounted from its typical £180+ retail price, making it exceptional value. Ideal for marathon training, recovery runs, or anyone with a history of joint pain. The 10mm heel-to-toe drop is moderate and forgiving.
ASICS Megablast — £224.95–£225.00
Best for competitive runners and track workouts seeking responsive energy return. The Megablast is ASICS's speed-focused offering, built around FlyteFoam Blast (a more reactive foam than Gel-Nimbus's version) and a carbon-infused plate for propulsive power. It's heavier on responsiveness, lighter on cushioning—think race shoe or tempo-run specialist rather than daily trainer. The tight pricing between the two variants (£224.95 vs £225) suggests stock variants with negligible differences; either is functionally identical. Better for 5K-10K runners or those training for shorter distances.
Quick Comparison
| Model | Price | Best For | Standout Feature | |-------|-------|----------|------------------| | Gel-Nimbus 27 | £80 | Long-distance, comfort-first runners | Gel + FlyteFoam cushioning; exceptional value | | Megablast | £225 | Speed work, racing, tempo runs | Carbon plate + FlyteFoam Blast for energy return |
What to Look For
- Cushioning type: ASICS uses Gel (shock-absorbing silicone) or FlyteFoam (lightweight foam). Gel feels softer initially; FlyteFoam offers faster ground feel. Choose based on whether you prioritise comfort (Gel-Nimbus) or pace (Megablast).
- Heel-to-toe drop: The Gel-Nimbus 27 has a 10mm drop (moderate), which suits runners wanting traditional shoe geometry without extreme angles. Check your current shoes' drop and aim for ±2mm.
- Weight: The Megablast is designed to be lighter for racing; the Gel-Nimbus prioritises cushioning over weight. If you run trails or uneven surfaces, prefer the heavier, more protective Gel-Nimbus.
- Pronation support: ASICS Gel models traditionally offer moderate motion control for overpronators. If you have flat feet or supinate (underpronation), the Megablast's stiffer design may suit you better; confirm with gait analysis at a running specialist.
The Bottom Line
The ASICS Gel-Nimbus 27 at £80 is the strongest buy here—it delivers premium cushioning at half its normal price and suits the vast majority of recreational runners training for distance. If you're racing or doing speed work, the Megablast at £225 justifies its cost through responsive design, though it's a specialist tool rather than an everyday trainer. For most people, start with the Gel-Nimbus; only upgrade to the Megablast once you've built a base and know your race distances.
Frequently Asked Questions
Is ASICS good value for money?
Yes, particularly the Gel-Nimbus 27 at £80—it's a significant discount on a shoe that typically retails at £180+. ASICS shoes generally last 300–500 miles before cushioning degrades, which works out to roughly £0.16–£0.27 per mile on the Gel-Nimbus; that's competitive with premium brands. The Megablast at £225 is priced fairly for a carbon-plated speed shoe, though it's a specialist purchase.
What's the difference between Gel and FlyteFoam cushioning?
Gel is ASICS's silicone-based shock absorber—it feels soft and absorbs impact well but is denser and heavier. FlyteFoam is a proprietary foam that's lighter and more responsive, offering faster ground feel and less energy loss. The Gel-Nimbus blends both; the Megablast uses FlyteFoam Blast for racing speed. For long runs, Gel feels more protective; for tempo work, FlyteFoam feels snappier.
Should I buy the Megablast or Gel-Nimbus 27?
Buy the Gel-Nimbus 27 if you're logging 20+ miles per week in training or doing marathon distance—it's designed for durability and comfort. Buy the Megablast if you're training specifically for a 5K or 10K race or enjoy fast-paced workouts; it's a pace-oriented tool, not an all-purpose trainer. Most runners benefit from owning both (one for long runs, one for speed work).
How long do ASICS shoes last?
Typically 300–500 miles of running before the midsole cushioning breaks down noticeably. The Gel-Nimbus 27, with its robust Gel system, tends toward the higher end; the Megablast, being lighter and designed for shorter races, may wear slightly faster under high-mileage training. Rotate between two pairs if possible to extend lifespan.
