The Saucony Endorphin Pro 2 is a neutral-oriented top-tier long-distance racing shoe built on an energetic foam midsole embedded with a curvy carbon-fiber plate that enhances forward propulsion.
It’s a featherweight and hyper-energetic PR machine and an ideal choice for your next 10K, half marathon or marathon.
The Endorphin Pro 2 was updated ever-so-slightly with more heel support, anti-slip laces for a more reliable fit and a new perforated mesh upper material for enhanced breathability. Those modifications helped improved the fit and feel without changing the essence of the super-responsive ride.
The new single-layer upper is made from recycled polyester. This has improved the fit and helps make the shoe more breathable and airy. The wrap-like fit is enhanced by Saucony’s FormFit technology, which allows the mono-mesh upper material to move and stretch slightly while still keeping feet locked down to the chassis.
The Endorphin Pro 2 fits true to size with a medium to low interior volume from heel to toe. It has a snug, locked-down feeling from heel to toe. There is a slightly higher volume in the arch area and modest wiggle room in the toe box.
There’s soft and comfortable step-in feeling in this shoe. That is thanks the premium footbed, gusseted tongue and thick midsole chassis. Combined with the curvy carbon-fiber plate embedded in the midsole, it results in a lively but very rigid rolling sensation the moment you start running.
The Endorphin Pro 2 is a race-day tool that is really good at up-tempo running but definitely not as good at slow to moderate paces. The similar Endorphin Speed 2 ($160) nylon-plated, training shoe handles those slower paces much better.
WHO IT’S BEST FOR
Runners interested in investing in a pair of carbon-plated racing shoes with the hope of setting a new PR in the 5K, 10K, half marathon or marathon will love this shoe.
While it could be used for faster workouts such as tempo runs and longer intervals, the sharp, firm feeling makes it much more conducive to racing than it is for training. (Imagine driving a high-end race car around town to do errands and you’ll understand the singular focus of the Endorphin Pro 2.)
PROS: SAUCONY ENDORPHIN PRO 2
The secret sauce of the Endorphin Pro 2 is the combination of Saucony’s PWRRUN PB midsole foam, the curvy carbon-fiber plate and SpeedRoll rocker geometry. PWRRUN PB is an ultralight, PEBA-based foam that provides an energetic and propulsive feeling in every stride.
The foam midsole chassis and firm plate are unchanged from the first edition. You can expect the same electric, responsive ride as the original edition of the Endorphin Pro.
Like other racing shoes with carbon-fiber midsole plates, the Endorphin Pro 2 feels best when you get into a groove at a fast and repetitive pace. When you settle into a conisisten rhythm, the sharp feeling of the chassis melts away into effortless running. But running at slower paces or mixing up paces will muddle that smooth, flowy feeling. Despite the responsiveness of the foam, the ride is unflinchingly sharp and rigid.
The outsole configuration of the Endorphin Pro 2 is identical to the original version. It features large sections of exposed foam complemented by high-abrasion carbon rubber in the forefoot and around the perimeter of the heel to keep the weight down, ensure optimal traction and maintain consistent durability.
CONS: SAUCONY ENDORPHIN PRO 2
The only detractor of the Endorphin Pro 2 is that it’s not very versatile. It’s a high-end racing shoe that can help you lower your PRs, but our wear-testers thought it felt too sharp and rigid to use for faster workouts or long runs.
