Our Verdict
ASICS NOVABLAST 5
Brooks Ghost Amp
The Brooks Ghost Amp and ASICS NOVABLAST 5 are both versatile daily trainers that aim to do it all, but the ASICS is the better shoe for most runners. It's more protective underfoot, offering a livelier ride. It's also lighter, and its midsole holds up better over longer efforts. The Brooks is still a good daily trainer, and its lower stack and drop mean it's more stable and suits runners who want a closer connection to the road.
