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.
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.
If you have flatter feet then running shoes with more cushioning is the way to go. Having extra material to absorb impact on ground strike will translate into more distance and less fatigue. Runners with a more neutral foot type can make selections that are considered more “middle of the road”. Make sure you also check the way that your old shoes wear on the outsole, this can tell you a lot about the way you step.
