The Winflo 4 is another of those discount Nike running shoes for women that mostly go unheralded—until runners start talking about their favorite models. The Winflo is like a stripped-down Pegasus, both in terms of price and weight: it comes in over an ounce lighter than its more-expensive sibling. The Winflo 4 uses the same Air cushioning in the heel, though, and the same engineered mesh and Flywire upper that has worked so successfully on Nike’s premium models that are praised for their snug fit.
