Supernova Prima 3 vs Ghost 18

The Supernova Prima 3 is adidas' comfort-first daily training shoe, a max-cushioned road trainer built to soak up easy miles and keep you fresh over the long run. With a 38mm heel and 8mm drop it sits firmly in the plush, protective camp, and the Dreamstrike+ foam is what gives it that soft, forgiving landing. This is not a shoe chasing pace. At 290g it is on the heavier side for a daily trainer, so you feel it more as a mile-eater than a snappy one. What you get in return is a smooth, stable ride that holds up well as fatigue sets in, helped by the Support Rods that add a touch of structure without turning it into a stability shoe. We rate it as a straightforward everyday running shoe for runners who value cushioning and calm over speed. If you want more energy return for tempo days, the lighter Supernova Rise 3 is the more versatile sibling.

The Brooks Ghost 18 is the shoe you reach for when you just want to run and not think about it. It is a smooth neutral daily training shoe, the workhorse end of the range, built to soak up easy miles and steady runs without fuss. The updated DNA Loft v3 midsole is softer and a touch more lively than older Ghosts, so it feels friendlier underfoot than the plain, dependable trainer this line used to be. With a traditional 10mm drop and a 36mm heel, it suits heel strikers and runners who like a bit of ramp under the foot. This is not a fast shoe and it does not pretend to be. At 289g it is on the heavier side, and there is no plate or snap here. What you get instead is consistency, a forgiving ride and the kind of shoe that just works, week after week. If you want one neutral daily trainer for the bulk of your running, the Ghost 18 is a safe, sensible pick. Runners chasing pace should look at the Nike Pegasus 42 instead.
