Altra builds all of its women’s shoes around its “Fit4Her” platform—a women-specific last takes into account the wearer’s narrower heel, higher instep, and longer arch. Add to that its zero-drop construction, which encourages natural foot positioning, a characteristic of Altra’s shoes. Compared to the 3.5, the 4 is slightly lighter according to tests at the RW Shoe Lab. For runners who have always wanted to give zero-drop shoes a go, the Torin 4 (or the even cushier Torin 4 Plush) is the perfect shoe to make the transition.

Mizuno completely redesigned the brand’s midsoles this year with a dual layer of foam in the shape of a wave, plus a full-length third foam level for even more cushioning. In the case of the Waveknit 3, the result is a shoe that feels softer, bouncier, and less stiff—without losing the smooth-riding qualities we’ve loved in Mizunos of yore. A more flexible knit Waveknit upper provides a snug fit with better stretch in the toebox than the Waveknit 2’s mesh upper. The durable rubber outsole is largely unchanged, adding up to a cushioned-but-firm trainer that will float you through your daily mileage.

Researchers have also found that because women tend to have wider hips than men, our feet are more likely to strike the ground toward the outside of our shoe soles. The inward rolling of the foot that results from this is known as pronation, which explains why more women are believed to overpronate than men. Some women’s running shoes account for this increased tendency with different materials used for support through the sole.
