Who it's for

Reach for the Topo Athletic Specter 3 for everyday training miles, long runs and tempo days and intervals. It's a neutral shoe, best for runners with an efficient stride who don't need pronation support. The tall, soft stack favors comfort over ground feel. That's great for high mileage and bigger runners, less so for racing snappiness.
