How the ASICS MegaBlast and Adidas Ultraboost 5 differ
The ASICS MegaBlast and the Adidas Ultraboost 5 sit in the same daily trainer bucket, so the question isn't what you'd use them for — it's which one matches your stride, your weekly mileage, and your budget.
Where they actually differ: the ASICS MegaBlast comes in roughly 2.3 oz lighter (8.1 oz vs 10.4 oz), which becomes noticeable on faster turnover and longer efforts; the drop differs (8mm on the ASICS MegaBlast, 10mm on the Adidas Ultraboost 5) — higher-drop shoes tend to feel friendlier to heel strikers and tight calves, while lower drops favor a midfoot landing; the ASICS MegaBlast uses a modern super-foam (PEBA or similar), which gives a livelier, more responsive ride than traditional EVA; and the Adidas Ultraboost 5 is $45 cheaper at MSRP ($225 vs $180).
