Durability is generally rated as good, with the outsole rubber holding up well and minimal wear after 50+ miles. However, exposed foam in the midfoot area is noted as a potential weak point, possibly reducing long-term outsole life compared to fully rubberized trainers.
The New Balance Fuelcell Supercomp Trainer is widely regarded by experts and users as an outstanding option for high-mileage daily training and long runs, thanks to its substantial cushioning, carbon plate, and stable ride. The v3's firmer PEBA midsole offers improved responsiveness and stability over v2, making it suitable for marathon training and extended efforts. Most reviewers highlight its comfort and ability to handle easy and moderate paces, with enough snap for tempo work, though it is not as propulsive or lightweight as top-tier racing shoes. The shoe is less ideal for racing due to its weight and less aggressive geometry compared to elite racers, but some runners still use it for half and full marathons. It is not designed for trail use, lacking traction and protection for technical terrain. For recovery runs, the plush cushioning and smooth rocker make it a gentle, forgiving choice, though some may find the carbon plate unnecessary for very easy days. Fit issues (notably a tapered toe box) may affect comfort for some, but overall consensus is highly positive for road-based, high-volume training.
Ideal for Best for intermediate to advanced runners focused on marathon or half-marathon training who want a high-cushion, plated trainer for long runs and tempo workouts. Suits those with a neutral gait who prefer a stable, energetic ride and are less concerned with plushness on easy days.
The SuperComp Trainer is designed for high-mileage training and long runs, especially for runners seeking maximal cushioning and energy return. The upper is breathable and adapts well to various foot shapes. The shoe is not legal for elite competition due to its high stack height but is favored for marathon training. Some users with very narrow feet may find the midfoot slightly roomy, but most report excellent lockdown and comfort for extended wear.
Sizing: True to size; most reviewers and fitting guides report standard sizing with no need to size up or down compared to other New Balance models or major brands.
