Saucony Xodus ISO RunshieldReview Facts

The release of the Saucony Xodus ISO Runshield trail running shoe came not too long after its predecessor. For the most part, the technology used is the same.  However, the Runshield version incorporates a bit more protection and a new kind of water resistant upper. The  Runshield version of the Xodus ISO is what the GTX version was for the old Xodus. These shoes are very comfortable and responsive. Reviewers say the ISO Runshield can easily help you tackle some the hardest off road runs.

Most reviewers had no problem with that Saucony switched out the Vibram XS-Trek outsole for their Saucony PWRTRAC outsole instead.  However, some have made it clear they are not very happy about that change. They think the grip and traction from the Vibram outsole was superior to the PWRTRAC.  Overall, these shoes feature plush cushioning, great responsiveness and a more durable and water resistant upper.

  • Water resistant

Outsole
Outsole

Outsole

The Xodus ISO Runshield features a totally new outsole from the previous Xodus. Saucony swapped out the Vibram X-Trek outsole for Saucont's PWRTRAC outsole. The highly durable rubber compound from the new outsole can get three time more traction than regular outsoles. These shoes perform well on a variety of terrain. The new outsoles provide excellent traction and are abrasion resistant. The lugs have an hexagonal shape that help provide additional traction when running over loose rocks or dirt. The rubber material is also very tacky, so you can run over wet surfaces with ease. Some reviewers have experienced reduced grip over time and claim that small rocks get stuck in between the lugs causing discomfort and reduced traction.
Midsole
Midsole

Midsole

The Runshield's midsole in the has been updated. The Everun midsole was designed and built by Saucony and promises to provide plush cushioning and great responsiveness. The Everun foam goes on top of a regular EVA foam providing dynamic responsiveness throughout the full length of the shoe. The transition from heel to toe is very smooth regardless of the conditions of the terrain. The sock absorption properties are really good and the energy return is outstanding as well. A ComforLite sock liner brings extra cushioning as well as impact protection.
Upper
Upper

Upper

The upper of the ISO Runshield is one of the best characteristics of the shoe. The FlexShell protects your foot, while the DWR material on the entire upper makes it water resistant. However, keep in mind these are not waterproof shoes. They will keep water out when it is raining and when you are running over wet surfaces, but they will not protect you when your foot is submerged in a puddle or river. The FlexShell upper is very breathable. Reviewers note that the ISO Runshield has a great combination of protection and breathability.

The ISOFIT dynamic system adapts to the natural movement of your foot. Reviewers have said it provides a really good sock like feeling. The overlays in the upper are made of FlexFilm material which is welded rather than sewn. Both, the FlexShell and the FlexFilm layers are seamless, lightweight and highly flexible. The shoe also has a RunDry lining to keep feet dry. The gusseted tongue keeps the debris out form the shoe. A toe shell provides extra protection to your forefoot as well as added durability to the upper.

Support

These shoes are known for their remarkable cushioning and support. Some reviewers have nominated them as an optimal shoes for running an ultra marathon. Its true that these shoes have incredible cushioning thanks to the Everun foam and flexible full length EVA in the midsole. The ComforLite sock liner also does a great job in cushioning and protecting you from the impacts. However, this shoe does not address any specific pronation issue. The insole in the Xodus ISO Runshield is removable, so if you over pronate or under pronate, we suggest you get insoles that will provide the right support for you.

The true value comes from what you really need in specifics. These are very durable with a maximalist approach. If that is what you're on the market for, these may be for you.

Traction

The rubber component of the PWRTRAC outsole provides great traction and grip over any surface. The TriFlex technology combined with the Everun technology increase the dispersion over a wider surface for better traction and control. Going up hill and down hill is easier when wearing the Xodus ISO Runshield. The outsole has two sections of lugs: half of them are facing forward and half of them are facing backwards. This makes for great traction when going up and incredible responsiveness when slowing down, breaking and going down hill.

The rubber compound is very durable and tacky. Running over abrasive surfaces will not wear down the tacky properties. The grip is remarkable when running on icy roads, climbing on wet rocks and running downhill on grassy paths. Some reviewers prefer the Vibram outsole in the previous versions in the Xodus line, but overall, the PWRTRAC provides just as good, if not better traction.

The ISO Runshield is more flexible than many other trail running shoes. They don't have an External Bedrock Outsole plate making them way more flexible than the usual Saucony trail running shoes.
