FuelCell SuperComp Elite v5 vs Streakfly 2

The FuelCell SuperComp Elite v5 is New Balance at its most serious: a carbon marathon racing shoe built to chase a personal best on the road and nothing else. This is a full super-shoe, with a PEBA midsole and a carbon plate that New Balance says is 38 per cent stiffer than before, and at 213g it is genuinely light for a shoe carrying this much foam. That combination is the whole point. You get a tall, energetic stack that protects your legs deep into a marathon, and a plate rigid enough to snap you onto your toes when you hold race pace. It sits right at the top of the road racing market on price at 220 pounds, up against the Nike Vaporfly 4 and the rest of the carbon crowd. We rate it as a true race-day tool. It rewards a committed effort and feels flat if you jog. Buy it to race, not to train.

The Streakfly 2 is Nike's short-distance specialist: a featherweight carbon racing shoe built to fly over 5K and 10K, not to baby your legs through a marathon. At 165g it is one of the lightest plated road racers you can buy, and that shows the moment you lift the pace. This is the rare super-shoe that stays nimble and low to the ground, so it turns and accelerates like a racing flat while still giving you the carbon snap you expect from a modern running shoe. Compared with the Vaporfly 4, which is built for the full and half, the Streakfly trades stack and long-haul cushioning for speed, agility and a more connected feel for the road. We rate it highly for parkrun PBs, track 5Ks and sharp interval sessions. At 170 pounds RRP it is a focused tool, and we would buy it knowing exactly what it is for.
