Cielo X LD 3 vs FuelCell SuperComp MD-X 3

The Hoka Cielo X LD 3 is a carbon-plated long-distance track spike, built for the 3000m, 5000m and 10000m rather than the road. This is a specialist racing shoe, not a trainer you rotate through easy miles. Hoka has leaned into propulsion here: a carbon plate paired with a firm, springy racing platform that wants to turn over fast and hold pace lap after lap. On the track it feels locked in and eager, and it rewards a runner who can sit on the plate and let it do the work. At RRP 220 pounds it sits at the top of the distance-spike market, alongside the fastest plated options from Nike and adidas. If you race the longer track events and want a plated spike that stays composed deep into a race, the Cielo X LD 3 earns its place. For the mile and under, its middle-distance sibling the Cielo X MD 3 is the sharper tool. This is a shoe for one job, and it does that job well.

The FuelCell SuperComp MD-X v3 is New Balance at full send: a carbon-plated middle-distance track spike built for the 800m through the mile and into 3000m. This is not a road shoe you can jog in. It is a racing spike, all pins and plate and pop, meant for hard efforts on the track and nothing else. At around 170g it is light without feeling flimsy, and the FuelCell foam under the carbon plate gives you more bounce underfoot than a traditional bladed spike, so you get some cushioning to hold form on the back half of a longer rep. New Balance sits it above their long-distance sibling, the SuperComp LD-X, which is tuned for 5000m and 10000m. In our view the MD-X is one of the sharper middle-distance super-spikes going, and a serious option if you race on the track and want plate-and-foam propulsion under a spike plate. Just know exactly what you are buying.
