Supernova Prima 1 vs Glycerin Max 2

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 Glycerin Max 2 is Brooks going all-in on soft, tall, protective cushioning. This is a max-cushion daily training shoe built for one job: swallowing up easy and recovery miles so your legs feel fresh the next day. With a 42.3mm heel stack and dual-density DNA Tuned foam underfoot, you sit high off the road and the landings are pillowy rather than snappy. At 305g it is a heavy running shoe, and it never pretends to be quick. There is no carbon plate and no pretence of speed. What you get instead is a big, forgiving platform and a smooth, rockered roll from heel to toe that keeps long slow runs comfortable well past the hour mark. In our view it sits at the plush end of the daily-trainer market, up against the Hoka Bondi 9 and Nike Vomero 18. If you want cushioning first and pace last, it delivers.
