Brooks Mens PureFlow The PureFlow brings a little more shoe and a whole lot of technology to a slick aesthetic. Neutral to Guidance runners can experience a run for the senses without losing the comfort of dynamic cushioning. With a wider Nav Band coming up the lateral side and grabbing the midsole, the foot receives arch support without the bulkiness of underfoot materials. A center strike pod provides guidance in finding the natural landing zone. Modern air mesh wraps the foot for an incredibly comfortable fit.
