I would encourage you to head to a local running store (not a Foot Locker) so they can assess your needs. Things they'll look for: height, weight, arch profile, forefoot width, running gait. They'll also want to know how many days a week you'll be running, miles per day, whether you'll run on sidewalks, paved roads/paths, or trails.
