ASICS Superblast 3 Review: The Ultimate Super Trainer for Triathletes
What to Look For in a High-Performance Running Shoe
The right running shoe can transform your triathlon training. ASICS has long been a favourite among triathletes for their blend of cushioning, responsiveness, and durability. With the Superblast 3 launching on March 1st, the brand is pushing the boundaries of what a super trainer can do — combining race-day speed with everyday training versatility.
Key Features to Consider
- Midsole Technology — Look for shoes with advanced foam like FF Blast Plus or FF Leap. These materials deliver bounce and energy return without sacrificing cushioning over long distances.
- Weight — A lighter shoe reduces fatigue on long runs. The Superblast 3 weighs around 220g, making it one of the lighter super trainers on the market.
- Versatility — The best triathlon running shoes handle both interval sessions and easy recovery runs. A shoe that can do both saves you money and simplifies your kit.
- Durability — Carbon-plated race shoes wear out quickly. Super trainers like the Superblast 3 use durable outsole rubber and can handle 400-600km before needing replacement.
Our Top Picks
Best Overall: ASICS Superblast 3
Launching March 1st at £210, the Superblast 3 is the most anticipated running shoe of early 2026. ASICS has upgraded the FF Leap foam for even more bounce, improved the outsole grip, and refined the upper for a more secure fit. It’s fast enough for tempo runs and cushioned enough for marathon training — the ultimate do-it-all shoe for triathletes.
Pre-order available from March 1st
Best Value: ASICS Novablast 4
At under £150, the Novablast 4 delivers impressive bounce and energy return without the premium price tag. The FF Blast Plus Eco foam is softer than the Superblast’s but still responsive enough for faster sessions. It’s an excellent choice for beginner to intermediate triathletes building weekly mileage.
Best Cushioning: ASICS Gel-Nimbus 28
If comfort is your priority, the Gel-Nimbus 28 is hard to beat. It’s 20g lighter than its predecessor and features updated FF Blast Plus Eco foam for plush cushioning on long, easy runs. Perfect for recovery days and ultra-distance training where protecting your legs is more important than speed.
Buying Tips
- ASICS shoes tend to run true to size, but if you’re between sizes, go up half a size for long runs to allow for foot swelling.
- The Superblast 3 launches March 1st — order early as previous versions sold out within weeks.
- Consider buying last year’s Superblast 2 at a discount if the new model is out of stock. You’ll get 90% of the performance at a lower price.
- Match your shoe to your training: Superblast for speed work, Nimbus for easy miles, Novablast for everyday training.
Care and Maintenance
To extend the life of your shoes, rotate between at least two pairs. This allows the foam to fully decompress between runs, maintaining cushioning and responsiveness. Air dry your shoes after wet runs — never use a heater or tumble dryer, as high heat breaks down the foam. Replace your shoes every 600-800km for cushioned trainers, or sooner if you notice reduced bounce or worn outsoles.
