Supernova Prima 1 vs Triumph 23

The Supernova Prima is adidas leaning all the way into soft, protective cushioning: a deeply padded max-cushion running shoe built for easy miles and long, gentle recovery days rather than speed. It sits above the daily Supernova Rise in the range, trading a little snap for a plusher, more forgiving ride underfoot. At 290g it is on the heavier side of the category, and with no plate and an 8mm drop this is a comfort trainer first and foremost, not a tempo tool. What you get for the £160 RRP is a smooth, cushioned road shoe that soaks up the pounding on higher-mileage weeks and keeps your legs feeling fresh. We rate it as a specialist rather than an all-rounder. If you want one shoe to do easy days and workouts, look elsewhere. If you want a dedicated cruiser for long, relaxed miles, it makes a strong case.

The Saucony Triumph 23 is the brand's premium max-cushion daily training shoe, built to soak up big weekly mileage in comfort rather than chase a fast time. It sits at the plush end of the neutral daily trainer market, with a tall 42.3mm heel stack and a soft, protective ride that rewards easy runs and long steady efforts. This is not a shoe you buy for speed. At 272g it is on the heavier side, and the 10mm drop plus generous cushioning steer it firmly towards comfort miles. What you get in return is a running shoe that stays kind to your legs at the end of a marathon block, when tired joints want padding more than pop. In our view it is one of the more dependable premium cushioned trainers you can buy, and a natural home for runners who log most of their week at conversational pace. If you already run the Triumph 22, the 23 is a familiar, refined step on.
