Adizero Adios Pro 4 vs Wave Rebellion Pro 3

Reviewers mostly liked how the Adios Pro 4 runs, and their complaints were about their toes. On speed they're close to unanimous: softer and bouncier than the Pro 3, a lot lighter, and properly quick once you're at 10k to marathon effort. The Run Testers found it lighter and cheaper than the Alphafly 3, if a little less springy. On fit, the toe box tapers, it runs a little short, and several testers had sore toes by the end of a marathon. So this is a carbon racing shoe for neutral runners with normal to narrow feet who race with some intent, from 5k up to the full distance. It's less happy at jogging pace or under a heavy heel strike. The newer Adios Pro 5 has a lower RRP and more padding at the heel, so check the price table before paying full whack for the older shoe.

The Wave Rebellion Pro 3 is Mizuno at its most uncompromising: a £250 carbon racing shoe built for one thing, chasing a fast marathon or half. The party trick is the radically cut-away heel, which drops away behind your foot and throws you forward onto a steep forefoot rocker. Land on your midfoot or forefoot and it rolls you through toe-off with real momentum. At 225g with a 4mm drop it is light and low-slung for a super shoe, and the carbon plate keeps everything firm and directional underfoot. This is not a do-everything racer. It rewards efficient runners who hold pace and land forward, and it can feel awkward for anyone who sits back on their heels. If you want a friendlier ride with more forgiveness, the Vaporfly 4 is the easier shoe to run. But for committed racers who like an aggressive, propulsive road shoe, few things feel this eager to move.
