Supernova Prima 3 vs Experience Flow 2

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 Experience Flow 2 is Altra's answer to runners who love the brand's roomy, natural feel but want a bit more snap. It is a lightweight daily training shoe that trades Altra's signature zero drop for a low 4mm, which nudges you onto your forefoot and helps the ride feel quick. At 238g it is genuinely light for a cushioned trainer, so it handles easy miles and picks up the pace for a tempo or progression run without feeling like a chore. Think of it as a do-most-things road shoe rather than a specialist. It is not a max-cushion recovery slab and it is not a carbon racer, but for daily running, faster sessions and the odd 10k it hits a sweet spot. If you have been curious about Altra's foot-shaped fit but found true zero drop a step too far, this is the easiest way in. In our view it is one of the more versatile shoes in the range.
