FuelCell SuperComp LD-X 3 vs Dragonfly 2

The FuelCell SuperComp LD-X 3 is New Balance's long-distance track spike, built for the 5,000m, 10,000m and steeplechase rather than the road. It sits at the sharp end of New Balance's racing line, a full-length carbon spike aimed at runners who live for the last lap. If your events are shorter and sharper, the SuperComp MD-X 3 is the middle-distance sibling, but for the long stuff this is the one. This is a running shoe in the loosest sense. It is a track weapon, stripped down and firm, with just enough FuelCell foam under a rigid carbon plate to give you propulsion without slowing the transition. At GBP 160 it is priced with the premium spikes it competes against. We rate it as a genuine championship-level option for distance track racing, and the steeplechase-ready build widens its appeal beyond the flat. If you race on the track and want carbon propulsion through every stride, it belongs on your shortlist. Just know it is single-minded: this is race day only.

The Nike Dragonfly 2 is a distance track spike, built for the 1500m up to the 10,000m rather than the flat-out sprints. Underfoot you get a slab of ZoomX foam paired with a Pebax propulsion plate, so it feels far closer to a super racing shoe than the bare, punishing spikes of a decade ago. That is the whole idea. You keep the light, locked-in, aggressive feel of a track spike, but the ZoomX gives you a little forgiveness so your legs are not shredded over a longer effort. At 145g it is genuinely light, and the 0mm drop with a low 19mm stack keeps you right down on the track for a fast, connected feel. This is a race-day tool, not a training shoe. If your event is 1500m and longer and you want a distance spike that lets you hold pace when it hurts, the Dragonfly 2 is one of the most trusted options out there. Sprinters and 800m specialists will want Nike's more aggressive Air Zoom Victory 2 instead.
