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 Glycerin 23 is Brooks at its plushest: a max-cushion daily training shoe built for the soft, unhurried side of your week. This is not a shoe chasing a personal best. It is the one you reach for on recovery days, easy miles and long relaxed runs when you want your legs coddled rather than told to work. The DNA Tuned midsole is deep and forgiving, with a tall 38mm heel stack and a moderate 8mm drop that suits heel and midfoot strikers alike. At 300g it is not light, and it never pretends to be fast, so if you want a snappy tempo shoe look elsewhere. What you get instead is comfort you can rely on, mile after mile, in a neutral running shoe that feels like it was tuned for pure cruising. If you want the same plush ride with a touch of support, the Glycerin GTS 22 adds guide rails. We rate it as one of the most dependable soft daily trainers going.
Putting two running shoes side by side shows the trade-offs quickly, but which one suits you still depends on how you run. Weight and stack height set the feel underfoot. A lighter shoe with a lower stack feels quick and nimble, and a heavier shoe with a taller stack gives a softer, more protective ride over long miles. Drop matters too: the lower the heel-to-toe drop, the more work your calves and Achilles do.
Prices come from the UK retailers we check every day. Best price now is the cheapest current price we can link you to. The 90-day low shows how cheap the shoe has been lately, and the 30-day average tells you whether today's price is a real drop or just what it usually sells for. If neither shoe is at a price you like yet, open its page and set a price alert. We'll email you when it falls.
