The New Balance FuelCell SuperComp MD-X v3 is a specialist track racing spike aimed at competitive middle-distance runners, with a design suited to fast sessions and races rather than everyday mileage. It combines FuelCell foam, a carbon-fibre plate and removable spike pins to create a responsive, track-focused platform.
New Balance lists an airy mesh upper, a traditional lace-up closure and a weight of approximately 168 g (5.9 oz). The foam is designed to feel propulsive, while the plate adds stiffness and the removable pins provide grip on appropriate track surfaces. Retailer information describes six removable pins and a race focus spanning middle-distance events.
The main attractions are low weight, secure track traction and a lively, structured underfoot feel. Limitations include reduced versatility on roads or pavements, a potentially demanding plate for runners unused to aggressive spikes, and the need to check event rules and track-surface requirements. This is not a substitute for cushioned training footwear.
The MD-X v3 uses unisex size conversions, so compare the men's and women's measurements carefully and try the shoes with the socks you intend to race in. Aim for a snug fit without cramped toes. Confirm permitted spike length before competition. The recorded US$169.99 is the official New Balance US listed price checked on 20 October 2026; size availability and retailer offers may change.
