Fit: Regular Saucony fit. Mesh upper adapts to the foot after 2-3 runs. Normal foot → usual size. Wide foot → consider half a size up. Brand comparison: fits similar to Brooks Adrenaline GTS, slightly narrower than ASICS Kayano, wider than Nike Structure.
Anti Use-Case
NOT suitable for: Neutral runners without pronation (need neutral shoes like Saucony Ride), supinators (need different lateral support), trail running (need dedicated trail shoes with aggressive grip), daily casual non-running use (too technical and expensive), speed/races under 4:00/km (too supportive, need racing shoes). For neutral runners, consult our neutral running shoes.
Competitor Comparison
Compared to Brooks Adrenaline GTS 24 (€140): Guide 18 lighter (-20g), lower drop (6mm vs 12mm), better price (-€40). Compared to ASICS Gel-Kayano 31 (€180): Guide 18 less bulky, more natural, excellent price (-€80). Compared to Mizuno Wave Inspire 20 (€130): Guide 18 superior PWRRUN cushioning, more balanced support. The Saucony Guide 18 offers the best value for money in the premium stability running shoes segment.
Maintenance and Care
Cleaning: damp cloth for mesh and upper, soft brush for outsole. NO washing machine (damages foams and structures). Natural drying away from heat sources, remove insole. Shoe rotation: alternate with another pair for superior durability. Lifespan: 600-800 km of running use (4-6 months for a runner doing 30-40 km/week). Replace when cushioning loses responsiveness or outsole shows excessive wear.

FAQ
How do I know if I need stability shoes?
If your foot rolls excessively inward during running (pronation), stability shoes help. Get a gait analysis at a specialized store.
Difference between Guide 18 and Guide 17?
Guide 18 has an improved, more breathable mesh upper, updated more responsive PWRRUN foam, reduced weight -10g, more anatomical fit.
Are they good for marathons?
Yes, excellent for marathons and half marathons. Cushioning and support last 42 km without failure.
How long do they last?
600-800 km of running use. For a runner doing 30 km/week = 5-6 months. Replace when cushioning loses responsiveness.
Can I use them for daily walking?
Yes, but they are oversized for walking. Better to use dedicated, more economical walking shoes.
