    It basically, overall, just handled pretty much everything I wanted it to.

  • 90 / 100 | Rob Andro | Level 4 expert

    I love what they've done. My only complaint is to fix its toe-box and give it a little more room and a little more breathability.

    ...it's still a good shoe and I'm ready for the race.

  • The Xodus ISO GTX is part of Saucony’s Run Anywhere line. It is built for long runs across the toughest of terrains under any condition, thus highly recommended for trail runners. With its semi-curved shape, the shoe is ideal for neutral pronators as they only require a moderate amount of arch support.
  • It features the brand’s signature PWR TRAC outsole that is designed to adapt to varying terrain. With the EVERUN™ technology in the midsole, the shoe is made firmer and more responsive compared to ordinary EVA foam.
  • The GORE-TEX® upper is waterproof and is designed to keep the foot dry while maintaining a breathable characteristic.

The waterproof version of the Xodus ISO has a standard running shoe length, so most wearers will find that it fits true to size. The forefoot and toe box heights are at a medium-low, which makes it more suitable for wearers with a low-volume foot. Runners who are looking for a maximum toe splay may want to get half a size up. Regarding width, the men’s version is D – medium while the women’s version is B – Medium.

With a 4-mm heel-to-toe offset, the Xodus ISO GTX delivers a more natural ride. It allows the foot and leg to exert moderate effort without having to rely too much on the cushioning and the stability features.

Featuring the PWR TRAC durable rubber, the outsole is capable of resisting abrasions while also delivering traction. Its sticky rubber component provides three times the traction than standard rubber. It is specially-engineered for optimal grip and mud shedding.

The gripping lugs have a hexagonal pattern to adapt to a variety of terrain.

The EVERUN™ technology is considered to be a breakthrough in shoe cushioning and aims to make the shoe livelier and more responsive. It results in smoother landings and stronger takeoffs without putting too much pressure on the heel and forefoot.

There is a molded ComfortLite sock liner that contours the heel and arch, thus reducing underfoot pressure.

The GORE-TEX® fabric in the upper is built to keep the foot dry as it keeps water out. It is also made breathable, so the foot remains well-ventilated, even during the most intense workouts. The result is an aggressive yet fluid and easy coverage.

The shoe also features the ISOFIT technology, which is a fit system that allows the shoe to morph to the foot for a customized feel. It creates a dynamic fit as it adapts to the shape and motion of the runner’s foot. ISOFIT creates a sock-like feel.

Featuring the RUNDRY collar lining, the Xodus ISO GTX makes sure that the heel and ankle are secure and free of moisture or sweat.

The molded toe shell and gusseted tongue prevent debris from entering the shoe.

A heel support frame aims to secure and guide the heel through the gait cycle.

It has a semi-curved last that is Strobel-stitched to make the underfoot experience in the Xodus ISO GTX more responsive and agreeable.
