Complete redesign, from toe to heel, is what the third version of the Saucony Zealot ISO has in store. Not so much in terms of technologies used, as many of them have already been seen in its predecessor, the Zealot ISO 2, but in terms of aesthetics and comfort of this training shoe for neutral runners, which is still a very versatile option.
Thus, leading technologies such as EVERUN, Tri-Flex or ISOFIT, among others, remain valid, and continue to prolong the success of the Saucony Zealot ISO 3 The changes that the American firm has tried to introduce are more focused on achieving a more aerodynamic design of the model. That is, the Saucony Zealot ISO 3 stands out for being a lighter model than its previous versions, but maintaining the optimal cushioning performance.
So, all the novelties of the Zealot ISO 3 are located in the upper of the model, in which Saucony designers have chosen to incorporate a new ISOFIT fit design, which means that the midfoot area is more wrapped, and appears seamless, increasing its comfort. This more comfortable and secure fit is also reflected in the rear of the shoe, as the heel has a new molded collar.
In the midsole, the 3 layer of EVERUN continues to provide energy return during the race. The EVERUN sockliner construction also adds to the cushioning and springy feel of the shoe.
Despite the fact that the Saucony Zealot ISO 3 does without the SRC Impact Zone system, the model does not give up that cushioned, soft and comfortable feeling underfoot. This is thanks, in part, to the new updated Tri-Flex outsole, which also improves flexibility, resulting in greater freedom of movement with every step.
In addition, the Saucony Zealot ISO 3 has also discarded the use of rubber reinforcements in the heel and midfoot area. This detail reduces the weight of the shoe, so the Saucony Zealot ISO 3 has a weight of240 grams in the men's version (size 42.5EU-9USA), and 206 grams in the women's model (size 39EU-8USA). The Zealot ISO 3 also has a drop of 4 millimeters.
