Cielo X1 2 vs Vaporfly 4

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 fourth Vaporfly is a shorter-race shoe now, whatever its marathon reputation says. Nike took it lower and firmer, and at 190g it's a very light carbon racing shoe to wear. Reviewers mostly agree the slimmer midsole suits 5k to half marathon better than 26.2. The Run Testers rated it best around the half and thought it short of cushioning for a full marathon unless you like a lower shoe. Believe in the Run graded its performance an A and its design a C, which is a fair summary: quick, but the heel fit lets it down. If you race shorter distances and found the v3 too soft, this is the better Vaporfly for you. If the marathon is your main event, the Alphafly 3 gives you more underfoot for the back half. The RRP is £260, and the price table below shows what UK retailers are asking now.
