# Training for 100 Miles: Why This Shoe Matters for Ultramarathoners
The New Balance FuelCell SuperComp Elite V5 has become the centerpiece of one runner's ultramarathon training program. For 100-mile trail racing, shoe selection goes beyond comfort. It determines how efficiently a runner covers extreme distances without injury.
The FuelCell SuperComp Elite V5 combines several features built for distance work. The shoe uses New Balance's FuelCell foam technology, which provides responsive cushioning without excessive weight. Carbon-plated shoes like this one improve running economy by reducing the energy cost of each stride. Studies show carbon plates can improve running efficiency by 2 to 4 percent, a meaningful advantage over 100 miles.
For ultramarathoners, shoe durability matters as much as initial comfort. The V5 iteration improves on previous versions with enhanced upper materials and a more robust outsole. Over the course of ultramarathon training, runners log substantial mileage. Shoes that break down create instability and increase injury risk during the taper leading into race day.
The shoe's geometry supports the specific demands of trail ultramarathoning. A wider toe box accommodates foot swelling during extended efforts. The heel-to-toe drop remains moderate, reducing Achilles strain common in ultra runners. Trail-specific outsole patterns grip varied terrain without excessive weight penalties.
Real-world experience from ultramarathoners training for 100-milers shows that shoe consistency matters. Many runners train in the same shoe they race in, which reduces variables and builds confidence. The FuelCell SuperComp Elite V5 tolerates the volume demands of ultramarathon preparation without compromising performance when race day arrives.
Choosing the right shoe for ultramarathon training requires testing during long runs. What works for a 10-
