As you would expect in a lightweight, low-to-the-ground shoe, the Boston features a sleek fit that best accommodates narrow to average foot types. For a lightweight trainer, the Boston feels very stable under the heel and through the arch area. A good go-fast shoe, the Boston offers the firm, responsive ride efficient runners look for in a lightweight trainer. A flexible forefoot promotes a fast transition, making this a great option for faster workouts and racing.
