Saucony Guide 13 Review

The men's Saucony Guide 13 in blue

The Saucony Guide 13 is an easy-riding stability running shoe.

A new PWRRUN midsole and lightweight TPU insert adds stability and Saucony’s FORMFIT technology gives the shoe bucket-seat-like security.

Fleet Feet testers took the Guide 13 on their regular training runs to test out Saucony’s updates. Here’s what they thought.

Saucony Guide 13 Fit and Materials

The Guide 13 is the successor to the Saucony Guide ISO 2, and the big difference between the ISO 2 and the 13 is the fit technology.

The Guide ISO employed Saucony’s ISOFIT tech, which Saucony says gave the midfoot a dynamic hold that molded to your foot shape and stride. Instead of ISOFIT, the Guide 13 uses FORMFIT.

FORMFIT technology uses three layers of cushioning that perform like a bucket seat in a sports car to give you a secure fit all around.

  • Top layer: conforms to your foot and changes as you run
  • Middle layer: adapts to stride and pressure points
  • Bottom layer: reactive and contoured to hold your foot in place

Fleet Feet testers say the Guide delivers a secure fit that doesn’t slip around while running.

“It’s comfortable right away,” one tester says. “The midfoot and heel are soft and snug, and I didn’t have any trouble getting the fit right the first time.”

Wrapped around the shoe is a lightweight mesh upper with slight stretch and enough give-in it to feel comfortable for a tester with wider feet, but it isn’t so stretchy that it feels baggy or loose.

“It feels true to size,” says another tester. “I have just enough wiggle room for my toes without it feeling too spacious or sloppy.”

Saucony Guide 13 Ride and Performance

The Guide rides exactly like the name suggests.

Runners who overpronate put more wear on the medial (inside) part of their shoes, which can lead to the shoe to break down inconsistently. Instead of the foam midsole wearing evenly from left to right, overpronators tend to wear out the medial foam before the lateral (outside), which can lead to uneven shoes.

For example: Picture a running shoe set on a table in front of you. If you look at it from the back, the shoe should look level from left to right. But an overpronator’s shoe might look like it’s leaning inward.

Many running shoe companies combat overpronation with medial support, and that’s exactly how the Guide 13 works.

“The Guide 13 feels surprisingly light and responsive for a stability shoe,” one tester says. “It has solid guidance for mild overpronators without being stiff.”

The PWRRUN midsole foam packed around the medial support gives the Guide 13 lightweight cushion. It’s not quite as soft as the PWRRUN+ foam used in the new Saucony Triumph 17, but it provides plenty of cushion for long runs.

Saucony Guide ISO 2 vs. Guide 13

The biggest changes from the Guide ISO 2 to Guide 13 are the previously mentioned fit tech and the cushioning.

Saucony transitioned from ISOFIT to the three-layered FORMFIT, and it swapped a PWRFOAM midsole and EVERUN topsole for a midsole made entirely of PWRRUN. But the shoe still has its signature medial post.

Saucony lists the latest Guide a little heavier for the women’s model (.3 oz) and a little lighter for the men’s (.1 oz). Either way, both male and female Fleet Feet testers felt like the Guide 13 was lightweight and responsive—especially for a stability shoe.

The new version also looks simpler than before. The Guide now sports a clean mesh forefoot and a lightly patterned midfoot.
