It's no surprise that Hoka One One, a brand known for its excellent cushioning, is on the list of shoes that benefit flat-footed runners. The Vanquish 3 makes use of materials such as carbon rubber to protect the foot from landing impact. Two layers of EVA foam are in place in the midsole to keep you comfy. The midsole also takes advantage of the brand's Meta-Rocker shape, which applies the smooth back and forth motions of a rocking chair to your feet.
