Brooks Ghost Amp vs Asics Novablast 6

The Ghost Amp is the more versatile, lighter trainer. At 255g men's / 227g women's with a 6mm drop, it suits tempo runs, speed work and long days, and owners report almost no break-in and good room for orthotics. The Novablast 6 is the bouncier, taller-stack option with an 8mm drop and FF BLAST MAX foam, but it is heavier at about 9.8 oz and its 4.1/5 rating shows more mixed owner feedback. Pick the Ghost Amp for all-round training and a lower, more stable ride; pick the Novablast 6 if you want maximum spring and a higher stack.

• Choose the Brooks Ghost Amp if you want one light, low-drop trainer for speed work, long runs and everyday mileage, with room for orthotics.
• Choose the Asics Novablast 6 if you want a tall, trampoline-spring ride and a higher 8mm drop for neutral road running.
