Cielo X1 2 vs Streakfly 2

The Hoka Cielo X1 2 is the brand's flagship carbon racing shoe, and it does racing in a way that is unmistakably Hoka: big, plush and stable rather than razor-light. It is a road racer built around a winged carbon plate and a deep, soft midsole, so you get a tall, protective ride that holds up when your legs start to fatigue late in a marathon. At 228g it is one of the heavier super shoes on the market, noticeably more than something like the Nike Vaporfly 4, and at £275 it sits right at the top of the price ladder. What you are buying is comfort and stability at speed, not the snappiest, lightest tool in the category. We rate it as a long-distance racer for runners who want a carbon shoe that feels planted and forgiving underfoot, and who will happily trade a few grams for that security over 26.2 miles.

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.
