Our Verdict
ASICS NOVABLAST 6
ASICS GT-2000 15
The ASICS NOVABLAST 6 is a better daily trainer than the ASICS GT-2000 15 for runners who prioritize practicality over added stability. It absorbs more impact under both the heel and forefoot, offers a softer feel, and maintains better forefoot protection over longer runs. That makes it a more appealing option for comfortable everyday mileage. The GT-2000 15 is better if you need a firmer platform with guidance features to prevent excessive inward rolling of your foot. It also has a roomier arch, although the very low toe box may press on higher-volume feet.
