Supernova Prima 3 vs 880 15

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 New Balance 880 v15 is the definition of a dependable neutral daily trainer: a road running shoe built to soak up steady miles rather than chase them. It sits in New Balance's line as the sensible, plush workhorse below the pricier Fresh Foam X 1080, and that is exactly its job. You get a tall, well-cushioned platform and a roomy, forgiving fit that suits easy runs, long runs and the daily grind of marathon training. It is a soft, protective ride first and foremost. At 286g it is on the heavier side, so this is not the shoe you reach for when you want to run fast, and there is no plate or standout tech giving you free energy at pace. What you get instead is comfort you can trust and an outsole that keeps going. For runners who want one reliable trainer to log the bulk of their week, we rate it as a safe, comfortable buy, if not an exciting one.
