We like the New Balance 870 because it is a super smooth go-to shoe for those of you who need a little something-something under the midfoot. It won’t get in the way either: It’s lightweight, buttery smooth from heel to toe (thanks! full ground contact midsole!) and gives you juuuust enough under the arch to guide a wayward roll forward. New Balance, which many people still think of as makers of your uncle’s favorite barbeque shoe, makes some of the very best lightweight trainers around. The 870 is one of them.
