The New Balance FuelCell SuperComp LD-X v3 is a specialist long-distance racing spike built for track competition. New Balance specifies a carbon-fibre spike plate tuned for events from 3,000 to 10,000 metres. FuelCell midsole foam aims to provide a lively, propulsive feel, while removable pins give traction on appropriate track surfaces. The lightweight mesh and synthetic upper is designed for breathability, and traditional laces allow fit adjustment. The manufacturer lists a shoe weight of 158 grams. These are not everyday road running shoes: the rigid plated platform and exposed spikes make them unsuitable for routine pavement training. Athletes should check venue rules on permitted pin length and surface type, especially when competing indoors. Review unisex sizing conversions and assess heel hold, forefoot room and comfort before buying. A tight racing fit should still allow natural toe movement without painful pressure. New Balance lists the model at US$169.99 before shipping and taxes. Prices and availability may differ by country and size.
