ASICS Megablast versus Dynafish Xiaonian - Which Supershoe is Best?

The ASICS Megablast is one of the most talked-about running shoes of 2025. But how does it compare to the Dynafish Xiaonian — the ultra-light Chinese super trainer that costs as little as £70 and has quietly built a cult following among running shoe enthusiasts? In this RaceDay running shoe review, I compare these two non-plated super trainers after real miles on the road. They might look similar on paper — big stack heights, lightweight builds, and modern foams — but once you run in them, they deliver very different experiences. I break down: • Weight and stack height differences • FF Turbo Squared vs TPEE foam • Ride feel and running efficiency • Stability and versatility • Upper, fit and build quality • Durability and outsole grip • Whether the £210 Megablast is worth it compared to the £70 Dynafish Xiaonian If you're looking for the best super trainer for marathon training, long runs, tempo runs or daily training, this comparison should help you decide.
