Our team of reviewers wore the Endorphin Shift 2 through long runs, hill workouts and cross training sessions and loved the lightweight, yet durable, feel.

Here’s everything you need to know about the latest update to the Endorphin Shift 2:

Endorphin Shift 2 Provides Plateless Propulsion

While the Endorphin Pro 2 and Speed 2 rely on carbon-fiber and nylon plating, respectively, the Endorphin Shift 2 provides plateless propulsion on the run.

Saucony designers bring together the best of SPEEDROLL technology and PWRRUN cushioning to create a responsive ride without the stiffness of a plate.

This makes the Shift 2 much more friendly for everyday training, as daily training in a plated shoe is not widely recommended.

The thick stack of PWRRUN foam and low offset height provides enough cushion and stability to last through blocks of high mileage and speedwork alike.

Our reviewers loved the responsive cushioning and rolling feel.

“I didn’t feel like I was digging myself out of cushioning on the run. I noticed the cushioning on landings, where I need it most, but otherwise these shoes pretty much melt away as soon as I put them on. They are so lightweight and bouncy, they handle hills and long miles really well,” says one reviewer.

In addition to the plushy, springy ride, the Endorphin Shift 2 provides personalized support with Saucony FORMFIT technology. This creates a 3D contour around the foot for ultimate support.

Designers combined FORMFIT with a removable, EVA sockliner to dial in the fit of the Shift 2 from the inside out.

“Even though these have a more traditional footbed fit, the sockliner and FORMFIT tech work really well together to create a huggy feel similar to the Endorphin Pro and Speed 2,” says one reviewer.

Revamped Mesh Upper Homes In On Breathability, Stability

The biggest update across the new Endorphin collection is a snug upper that supports the foot, especially around the heel collar. The Endorphin Shift 2 is no exception.

Unlike its Pro 2 and Speed 2 cousins, the Shift 2 features an external TPU heel counter that adds both swagger and stability to the overall feel of the shoe. Compared to the original Endorphin Shift, this heel counter is more streamlined and provides more specific support along the heel.

“I usually don’t look for heel support, but these feel snug in all the right places, especially when I’m doing speedwork,” says one reviewer.

Along with the new heel counter, the Shift 2 uses an updated heel collar fit to create a greater sense of security while running at top speeds.

In addition to the updated heel fit, a thinner engineered mesh upper enhances the ventilation of the Shift 2, adding to the overall lightweight, airy feel.

“These shoes have a super clean look,” says one reviewer. “I love the mesh upper, it’s very flexible but sturdy enough to support my foot over hard efforts and speed work.”

The original version of the Endorphin Shift used a sandwich mesh upper for added padding. Since the updated Shift 2 uses a sockliner, the mesh is now much thinner, yet still uses a perforated knit for maximum breathability.

Durability is no question with the Endorphin Shift 2. The outsole is constructed from XT-900 blown rubber and features reinforced high-abrasion zones for better traction on slick roads or tracks.

If you’ve run in the original Endorphin Shift, the biggest difference you’ll notice when upgrading to the Shift 2 is in the fit.

Between the single-layer mesh upper and updated non-slip lacing system, the Shift 2 offers a much more dialed-in fit without the bulk of the previous model.

Sleek fabric and padding in the heel collar creates a huggy feel that eliminates uncomfortable rubbing, while a more specifically designed plastic heel counter provides just-right support over long efforts and speed work.

Final Thoughts

The Saucony Endorphin Shift 2 is possibly the most accessible shoe out of the Endorphin collection. The lack of plating elminiates stiffness that may be uncomfortable to runners looking for an everyday trainer, but the Shift 2 does not compromise on cushion or speed.

The lightweight PWRRUN midsole foam is poppy and responsive and, in combination with the SPEEDROLL geometry of the shoe, creates a rolling, effortless feel on the run.

An updated upper and cushioned heel collar work to support your foot in all the right places, providing stability where you need it most. Together with an updated no-slip lacing system, the Shift 2 really lets you personalize the fit of your shoe for any activity.

The thick stack of cushioning foam and sleek look of the Endorphin Shift 2 make it a great option for runners and walkers alike.
