The Saucony Guide series has built a solid reputation among runners seeking a blend of stability and comfort.

After a complete overhaul of the Guide 17 last year, this new edition continues the same modern approach to stability, without a rigid medial support.

This new version stays true to its fundamentals while bringing some subtle adjustments.

But is this continuity enough to justify a new purchase? Does this shoe suit your runner profile?

That’s what we’ll find out in this comprehensive review.

Our Verdict

Cushioning

The Saucony Guide 18 retains the technologies that made the previous version successful. It features a PWRRUN foam midsole, paired with a PWRRUN PB insole for a bit more responsiveness.

The height remains identical with 35mm at the heel and 29mm at the forefoot, for a low drop of 6mm.

The cushioning of the Guide 18 offers a balanced, classic feel. Coming from a much softer Nimbus 27, the difference is quite striking, even if the comfort is there.

I particularly appreciated the shock absorption level, which remains effective even after many kilometers. No sensation of fatigue or “hard-striking” shoe on long runs of 15-20 km. I’m not at this level at the moment, but I could see it as an option for a marathon.

Energy Return

With a weight of 272g for a size 42 in men’s shoes, the Guide 18 remains average for modern stability shoes. It’s slightly heavier than the Saucony Ride 18 (259g), but notably lighter than an Asics Gel-Kayano 31 (300g).

In terms of dynamism, the Guide 18 doesn’t reinvent the genre. The PWRRUN foam offers moderate energy return. There’s no trampoline effect of the new PEBA foams in the Endorphin models.

However, heel-to-toe transitions remain smooth thanks to the well-thought-out sole geometry.

The shoe responds well to easy paces and long runs but shows its limits when trying to seriously accelerate.

Stability

The Guide 18 retains the Center Path technology, Saucony’s modern approach to stability. Gone is the traditional medial post (rigid reinforcement) found in old versions.

This technology is based on a redesigned geometry with a wider base and raised sidewalls that “cradle” the foot. The result is a more natural and less intrusive stability. It aims to keep the foot on track without forcing the correction.

I’m not a pronator, so it’s hard to determine its effectiveness compared to orthotic insoles, for example. Remember that the evidence supporting pronator shoes reducing injury risk is insufficient.

Either way, I found the stability to be good. For instance, there’s a bit more structure than on a Nimbus 27.

Foot Lockdown

The upper of the Guide 18 has been subtly improved to offer a more precise fit.

The technical mesh provides an excellent balance between support and breathability. I particularly appreciated the elasticity of the mesh, which adapts well to different foot shapes without creating pressure points.

Comfort is ensured with strategically placed padding at the collar and tongue. I didn’t experience any irritation or friction points. The tongue is held in place by a gusset system that prevents any lateral slipping.

The semi-rigid heel counter ensures good rearfoot support without being too restrictive. As for the lacing system, it’s classic but effective, allowing for a precise adjustment according to individual preferences.

The Guide 18 fits true to size and offers standard interior volume. There’s also a wide version if needed.

Traction

The Guide 18’s outsole uses strategically placed XT-900 rubber on main wear zones while leaving some exposed foam areas to reduce weight.

This setup offers satisfactory grip on dry asphalt and typical urban surfaces. On wet terrain, performance remains decent but requires caution (e.g., damp tiles).

Sole flexibility is well-balanced, allowing for a natural foot roll without being too stiff or too soft. Strategically placed flex grooves help maintain fluid movement.

The Guide 18 performs well on typical urban surfaces and can venture on non-technical trails, but it’s clearly not designed for trail running.

Use scenarios

The Saucony Guide 18 excels in its primary domain: daily training and long runs. The combination of comfortable cushioning and subtle stability makes it an ideal choice for extending distances at easy paces.

I particularly appreciated its versatility on runs ranging from 10 to 25 km.

The Guide 18 can also be a great option for a marathon if you prioritize comfort and stability over pure performance.

The Guide 18 feels a bit sluggish for fast intervals but handles tempo runs without issues.

If you’re looking for a more responsive stability option, the Saucony Tempus 2 might be an interesting choice.

Beginners will also appreciate its reassuring stability, while experienced runners may find an interesting stable variant for their rotation.

Quality and Longevity

The Saucony Guide 18 boasts solid construction with quality materials. The PWRRUN foam retains its properties over time, although this may vary depending on your weight and stride.

The stretch mesh remains robust, and I didn’t notice any signs of wear after my sessions.

As mentioned earlier, the outsole is a weak point with limited rubber coverage, leaving quite a bit of exposed foam.

It’s too early to judge the impact of this setup, but I’ll keep you informed if there’s significant evolution.

As it stands, the quality-to-price ratio is good and befitting of a Saucony.

These shoes are vegan but contain only a small amount of recycled materials.

Conclusion

The Saucony Guide 18 reaffirms its status as a reference in modern stability shoes. This new edition continues the previous trend and brings minimal changes.

Its main highlights remain its balanced and comfortable cushioning, its relative lightness for a pronator model, and its impeccable support. All at a fair price for the quality.

If you have mild or moderate overpronation, or simply seek a stable model to increase distance up to a marathon, the Saucony Guide 18 is one of the best options.
