Shoe Review: Saucony Endorphin Speed

The Saucony Endorphin Speed running shoe

The Saucony Endorphin Speed brings approachable performance to your training.

Saucony created the Speed as the middle shoe in the Endorphin collection—a three-pack of shoes that also includes the base model Saucony Endorphin Shift and the souped up Saucony Endorphin Pro. The middle child blends the versatility of an everyday trainer with the performance of a race-day shoe.

A new PWRRUN PB foam powers the Speed from beneath and a nylon plate adds just-right stiffness for speed workouts or racing.

Fleet Feet reviewers took the Saucony Endorphin Speed out for their daily runs and workouts to check out how it fits and how it performs. Here’s what they thought.

Saucony Endorphin Speed Fit and Materials

The Saucony Endorphin Speed is built for uptempo paces, and its materials and fit reflect that.

Saucony built the Speed with a lightweight engineered mesh upper to make the shoe easier on your legs; the ventilation holes are big enough to see your socks through, so they help keep your feet cool.

One Fleet Feet reviewer said he wore the Endorphin Speed on one of the hottest days so far this year, and his feet didn’t feel swampy.

Two features set the Speed apart from the other shoes in the Endorphin pack: a nylon plate and enhanced foam. Together, the two components create what Saucony calls Speedroll Technology, which helps you roll efficiently from landing to toe off.

Saucony used its PWRRUN PB foam underfoot. The newest PWRRUN foam composition is the lightest and springiest foam Saucony makes, so it’s perfect for a speed shoe.

Packed inside the foam is a full-length nylon plate. Like running shoes with carbon-fiber plates, Saucony’s nylon version creates a propulsive feeling. The nylon, though, is more flexible than carbon fiber, making the Endorphin Speed a tamer version of the carbon-fiber-plated Saucony Endorphin Pro. This also makes it better suited to training than the pure-speed of the Pro.

The Speed has an accommodating fit. It fits about the same as the classic Saucony Ride 13, with a comfortable toe box and midfoot, and the internal heel cup locks your foot into place.

The tongue and heel cup are minimally padded, and the upper only has a few printed overlays, including the Saucony logo on either side of the shoe.

Saucony Endorphin Speed Ride and Performance

The Endorphin Speed is an ideal blend of comfort and performance, making it a great bridge between your daily drivers and your racing flats.

The PWRRUN PB foam feels very responsive underfoot. It’s soft and comfortable on landing, but it provides quick feedback.

Like other shoes with plates, whether carbon-fiber or plastic, reviewers said the Speed feels best at faster paces. The combination of the premier foam and the plate create serious pop off the toe, which only gets better with a midfoot to forefoot strike.

“The Speed really shines when I’m moving fast,” one reviewer says. “It feels like it’s asking for a quick turnover.”

But that doesn’t mean the Endorphin Speed can’t handle cruising, too. Warm up with an easy jog to the track, and then kick it into high gear for a speed workout; the Speed will pull double duty as a high-mileage trainer and a PR-hawking performer.

One of the major benefits of the Endorphin Speed is its feathery weight. At 6.8 oz for the women’s model and 7.8 oz for the men’s, the Speed doesn’t hold you back. It feels nimble and light on the run, which testers loved.

“Saucony didn’t go overboard on anything here, which is nice” says another tester. “It has just the right amount of foam underfoot and not too much padding anywhere to keep the weight down. It looks and feels light.”

Beneath the shoe, Saucony tacked on an abrasion-resistant rubber outsole. The bulk of the rubber coats the forefoot, but a ring of rubber runs around the edge of the midfoot and heel. The foam is exposed in the middle of the shoe.

One big difference between the Speed and other everyday trainers, like the Ride 13, is the shape of the midfoot. Designers pinched the midsole in at the midfoot, like they cinched a belt around the shoe’s waist. The shoe’s design encourages midfoot to forefoot strike that you naturally experience when you run faster.

The shoe also employs Saucony’s proprietary Speedroll technology. This is the combination of the shoes’ shapes, foams and stiffness. Saucony says the combo aligns a runner’s hips for a more effective stride, reduces stress on feet and joints, and improves efficiency.

Saucony Endorphin Collection

The Saucony Endorphin Speed is the mid-tier shoe in the brand’s three-shoe Endorphin Collection.

The unifying feature is Saucony’s new Speedroll Technology, but each model is tuned for a specific purpose:

  • Endorphin Shift. The Shift is the base model in the pack. Think easy, recovery days or maintenance miles.
  • Endorphin Speed. Saucony’s middle shoe blends speed and comfort with a more flexible nylon plate. Great for speed workouts and uptempo days.
  • Endorphin Pro. A carbon-fiber plate powers the fastest shoe in the collection. Ideal for race day. In fact, Molly Seidel wore a fresh pair at the US Women’s Olympic Marathon trials, where she placed second.

Each shoe goes about it a little differently, but the goal is the same: to give you a running shoe tailored to each aspect of your training while maintaining a familiar feel.

The Saucony Endorphin Speed bridges the gap between your everyday trainers and your racing shoes.

Designers shaped the Speed for a comfortable fit that’s easy on your feet even as the miles add up. The lightweight upper lets the shoe breathe easily, and the nylon plate pairs well with the ultra-springy PWRRUN PB foam for a propulsive ride.

Fleet Feet reviewers like the Speed for runs that vary in pace because it handles different speeds well.

“I love the Speed’s versatility,” one reviewer says. “It excels at fast paces but can handle a warmup and cooldown just fine.”
