The New Balance FuelCell SuperComp Trail is the trail-racing equivalent of road shoes like the New Balance SC Elite v3, using the brand’s bouncy FuelCell foam and a carbon plate in the midsole. It’s one of the best trail-running shoes for those seeking a racer for a range of events, but I’m not sure it’s comfortable enough for ultra-marathons, where the Nike Ultrafly and Adidas Terrex Agravic Speed Ultra stand out as better options.
