Alphafly 3 vs Endorphin Pro 5

The Nike Alphafly 3 is the brand's maximalist marathon racer, the carbon racing shoe built to carry you to a road PB and not much else. It pairs a full-length carbon plate with twin forefoot Air pods and a tall slab of ZoomX foam, so you get a ride that is bouncy, propulsive and unapologetically built for going long and fast. At 218g it is not the lightest super shoe on the shelf, but the energy return more than earns the few extra grams once you settle into marathon or half pace. This is a specialist. It rewards a committed forefoot or midfoot strike and a pace you can actually hold, and it feels flat and over-built if you jog it easy. If you want a slightly lighter, more nimble option for shorter races, the Nike Vaporfly 4 is the natural stablemate. For the marathon, though, the Alphafly is the one we reach for.

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.
