Verdict

Still the reference marathon shoe. The Air pods give a propulsive forefoot that nothing else quite replicates, and the wider platform makes it manageable late in a race when your form has gone.

■ Caution

Sits at exactly 40mm — legal, but with no margin. It is a lot of shoe for anyone racing slower than about 4:30/km, and the forefoot pods reward a genuine forefoot strike.
