The Turbo 2 is built for women who want to go fast, with a soft, springy ZoomX foam in the midsole borrowed from the record-setting Vaporfly Flyknit 4%. Typically, an EVA foam midsole will compress easily and then take its sweet time recovering shape. But ZoomX technology has blown us away with its quick compressibility and immediate rebound. Nike has added a thin layer of React foam to the bottom so the shoe will hold up for longer, as well as a rubber outsole grid for traction. Overall, this is a high-mileage, versatile shoe that combines the fit and feel of a workhorse Pegasus with the lightweight speed of a racing flat. Just be warned that upper feels slightly less secure than the first Peg Turbo.
In general, women tend to have 15% lower body mass than men, this means shoes must have a deeper groove that can provide greater flexibility, which, translates to a smooth and natural toe-off motion through the running patterns of the foot. Seasoned runners agree that a little less foam in the overall cushioning of a running shoe goes a long way for female runners.
First off, women’s shoes share a few features based on characteristics that may or may not apply to you. It’s possible you might prefer a “men’s” shoe, just as some men might feel more comfortable in a “women’s” shoe. The designs of the shoes are just based on general group tendencies—such as that women have less muscle mass than men and tend to weigh less as a result. For this reason, women’s shoes often have a lighter and softer midsole to make up for the lower degree of impact put on the shoe with each stride.
