Our read

The FuelCell SuperComp MD-X v3 is a purpose-built track spike, not a road shoe. Its PEBA midsole and carbon plate with removable pins deliver the bouncy, propulsive feel reviewers repeatedly praise across sprint and middle-distance events. It is worn by global title winners, but its narrow race-only construction and quick-wearing heel foam mean it belongs strictly on the track.

Ride

Highly responsive and bouncy underfoot thanks to high-rebound PEBA and an industry-leading carbon plate with removable pins, tuned for propulsion at race pace on the track.

Fit

Runs small and narrow per aggregate fit ratings (2.73/5 fit, 1.89/3 width); this colorway reportedly runs even smaller than others. Consider sizing up.

Best for

Track athletes racing middle to long distances (400m through 5000m) who want a light, propulsive PEBA spike.

Avoid if

You need a shoe for road, walking, or any surface off the track — the heel foam wears fast and concrete use is not recommended.
