The Saucony Endorphin Speed 2 is a light, cushy and extremely energetic everyday training shoe. It’s amazingly comfortable and infinitely versatile.
The secret sauce of this shoe is the combination of the lively PWRRUN PB midsole foam and how the semi-firm curvy nylon helps create seemingly effortless forward propulsion.
Our wear-testers believe it’s one of the best shoes of 2021.
The Endorphin Speed 2 has been slightly updated a new mono-mesh upper. This is made from recycled materials, has a snugger fit in the heel, anti-slip laces and some soft, suede detailing.
The new upper made from recycled nylon has improved the fit but also helped make the shoe more breathable and airy. The wrap-like fit is enhanced by Saucony’s FormFit technology, which allows the upper material to move and stretch while still keeping feet locked down to the chassis.
The outsole configuration on the Speed 2 is identical to the original version. It features vast 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.
The bottom line is that it’s been tweaked slightly without changing the spirited essence of the original Endorphin Speed.
The Endorphin Speed 2 fits true to size with a medium to low interior volume from heel to toe. It has a slightly lower volume in the arch area, good wiggle room in the toe box and a snug feeling in the heel.
The step-in feeling is soft and secure with a very noticeable light and bouncy sensation the moment you start running in them. While the curvy nylon plate and advanced foam create a sprightly vibe at up-tempo paces, the shoe feels equally as comfortable and peppy on longer and slower runs.
At top speed, the shoe feels almost effortless with just a tad less energetic pop than the Endorphin Pro 2 ($200) carbon-plated, race-day shoe at the top of the line. But it’s the versatility of being able to handle all types of running with aplomb that make the Speed 2 such an amazing shoe.
WHO IT’S BEST FOR
Runners who appreciate shoes with a light, soft and animated ride will really enjoy running in the Endorphin Speed 2.
It’s not quite as high off the ground as some maximally cushioned shoes, but it’s not a low-to-the-ground lightweight performance-oriented trainer, either.
It’s versatile enough to run long, run fast, run slow and just about everything in between. It could also be a good choice for racing from mile to the marathon.
If you’ve previously run in Saucony’s Kinvara, you’ll find the Endorphin Speed 2 to be a premium upgrade.
PROS: SAUCONY ENDORPHIN SPEED 2
Saucony’s PWRRUN PB is an ultralight, PEBA-based foam that provides a bouncy and propulsive feeling in every stride and at every pace. That foam midsole chassis is unchanged from the first edition, so you can expect the same agile and responsive ride.
Like the original version, the Endorphin Speed 2 has a curvy, rocker geometric profile that contributes to what Saucony calls SpeedRoll technology. Combined with the nylon plate and energetic foam, it creates a lively, forward-rolling sensation at every pace.
Versatility is the name of the game for the Endorphin Speed 2. Whatever you ask it to do — long runs, recovery runs, speed work, tempo runs, short races, long races — it will do it with a high-performance, energetic zeal.
If you’re looking for a do-everything model as the only shoe in your quiver, this is a great one to consider.
CONS: SAUCONY ENDORPHIN SPEED 2
Honestly, there’s nothing to dislike about this shoe. However, if you appreciate shoes that are lower to the ground or shoes with a less bouncy ride, this won’t be the one for you.
