  1. Good All Around Shoe 5 Star Review

    Posted by

    I bought this as a replacement pair of pt shoes. Good traction, durable and breathable outer portion. If you're an avid runner, they're good for trails, slightly heavier than normal running shoes and very comfortable to my feet. I'm even considering buying another pair while they are on sale.
