With their fourth iteration of the popular model, designers of the Saucony Hurricane ISO 4 look to increase both the cushioning and flexibility of the shoe without compromising the support level. In order to enact these changes the midsole, outsole, and upper were reviewed and completely redesigned.
The most impactful update to the Saucony Hurricane ISO 4 is the shift from a PWRGRID+ midsole with an EVERUN insert at the heel to a full-length EVERUN midsole. The EVERUN compound has proved to be more flexible and to deliver a much more responsive feel than previous cushioning technologies. As a result of this change, the Hurricane ISO 4 should provide ample cushioning as well as a flexible ride that has plenty of underfoot spring. However, the shoe should not come with any decrease in support, as the Hurricane ISO 4 includes a retooled dual density EVA post that should maintain support levels while delivering a smoother ride.
To even further increase the flexibility, the outsole of the Hurricane ISO 4 has a new flex groove design that improves the shoe’s ability to bend with uneven surfaces. The update should not result in a significant change in the level of traction though.
Further modifications were made to the ISOFIT engineered mesh upper that aim to improve both the fit and the durability. Three primary points to note are the reconfigured lace structure, an updated engineered mesh, and an added overlay above the big toe. In concert these changes should make the shoe more comfortable while preventing wear and tear.
In spite of the numerous updates, the weight of the Hurricane ISO 4 only differs from that of its predecessor by a small margin. The reported weights for the men’s and women’s Hurricane ISO 4 are just 0.1 and 0.3 ounces heavier than the respective production models of the Hurricane ISO 3.
