Metaspeed Sky Paris vs Vaporfly 3

The Metaspeed Sky Paris is ASICS at full race trim: a carbon racing shoe built for one job, chasing a personal best on the road. It is the cadence runner's racer, the half of the Metaspeed line tuned for runners who get faster by keeping their stride length and turning their legs over quicker, while the Metaspeed Edge Tokyo handles those who lengthen their stride. At 215g with a full-length carbon plate and a 5mm drop, it is light, aggressive and unmistakably a marathon shoe rather than a do-everything trainer. The bouncy, springy foam and stiff plate work together to roll you forward and reward a committed effort. Hold goal pace and it comes alive. Jog it easy and you will wonder what the fuss is about. In our view it sits right at the top of the carbon racing shoe pack alongside the Nike Vaporfly 4, and at £260 it is priced like the elite tool it is.

The Vaporfly 3 is Nike's carbon racing shoe for runners who want to go fast without the towering stack of an Alphafly. It is a pure road racer, built for 5k up to the marathon, and it does that one job very well. At 194g it is light, the 8mm drop keeps you rolling forward, and the carbon plate gives you real pop when you commit to race pace. This is not a shoe for plodding. It rewards a quick, efficient stride and comes alive the harder you push. If you have run in earlier Vaporflys you will know the feeling: fast, slightly twitchy, and unmistakably a tool for race day. The newer Vaporfly 4 refines the formula, but the 3 remains a serious marathon shoe, and when it drops below RRP it is one of the better-value carbon racers you can buy. We rate it for runners who already have a daily trainer and want a dedicated PB weapon.
