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.
I'm in my running shoes a lot: I've set out to run a marathon in 30 different countries, raising money for local organizations in each one. Running race after race, I look for comfort and reliability in a shoe. I want to be sure every day that I'm getting the same fit as I did the week before, and that my feet are happy after 18 months of travel and running.
