Dragonfly 2 vs Endorphin Pro 5

The Nike Dragonfly 2 is a distance track spike, built for the 1500m up to the 10,000m rather than the flat-out sprints. Underfoot you get a slab of ZoomX foam paired with a Pebax propulsion plate, so it feels far closer to a super racing shoe than the bare, punishing spikes of a decade ago. That is the whole idea. You keep the light, locked-in, aggressive feel of a track spike, but the ZoomX gives you a little forgiveness so your legs are not shredded over a longer effort. At 145g it is genuinely light, and the 0mm drop with a low 19mm stack keeps you right down on the track for a fast, connected feel. This is a race-day tool, not a training shoe. If your event is 1500m and longer and you want a distance spike that lets you hold pace when it hurts, the Dragonfly 2 is one of the most trusted options out there. Sprinters and 800m specialists will want Nike's more aggressive Air Zoom Victory 2 instead.

The Endorphin Pro 5 is Saucony's carbon marathon racer, and the fifth version is the most complete one yet. This is a road racing shoe built around a slotted carbon SpeedRoll plate sitting in a stack of PWRRUN PB and Super Critical foam, so you get that firm, rockered snap through toe-off that the Endorphin line has always chased. At £225 it lands squarely in the super-shoe bracket alongside the Nike Vaporfly 4 and adidas Adios Pro, and it earns the price if you are racing anything from 10k to a marathon. Compared with the Endorphin Pro 4 it feels a touch more planted and a little more forgiving on tired legs, without losing the rolling geometry that makes it want to move at pace. In our view this is a proper PB tool, not an everyday cruiser. Buy it to race, and it delivers.
