Adizero Avanti 2 vs Cielo X MD 3

The Adizero Avanti 2 is adidas at its most single-minded: a long-distance track spike built for the 5000m and 10,000m, and not much else. This is a race-day tool, not a training shoe. At 170g with a stiff full-length spike plate and Lightstrike Pro foam underfoot, it aims to give you a touch more cushion and return than a stripped bare spike, so your legs survive 25 laps and still have a kick left. On the track it feels fast and direct, with the pins biting hard through the bend. We rate it as one of the more forgiving distance spikes out there, which matters when the gun goes on lap 20 and not lap 2. It sits mid-pack on price for an elite spike at an RRP of 150 pounds. If you race longer track events and want a spike that protects you late, it earns a place in the bag. Shorter, sharper efforts want a different tool, and the Adizero Ambition 2 covers the middle distances better.

The Cielo X MD 3 is Hoka's middle distance track spike, built for the sharp end of the 800m through the mile and up to 3000m. This is a specialist racing shoe, not a trainer, and it makes no apology for it. A PEBA midsole sits over a carbon plate on a low 19mm heel and 16mm forefoot stack, so you get a fast 2.7mm drop that keeps you up on the ball of the foot where a middle distance runner wants to be. Six removable pins bite the track and the plate snaps you through each stride when you are turning the legs over hard. At GBP 225 it is a serious investment aimed at competitive club and collegiate athletes, and it goes head to head with the New Balance SuperComp MD-X. If your races are longer, its sibling the long distance model suits you better.
