What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Vibram XS Trek outsole delivers excellent traction on wet rocks, loose scree, mud, and technical surfaces
- Gore-tex surround technology provides waterproofing with better breathability than standard waterproof shoes through molded aeration channels
- Stiff midsole and toe/heel bumpers protect feet well on rocky and uneven terrain
Reviewers push back
- Narrow toe box squashes toes, especially on downhill sections, uncomfortable for wider feet
- Heavier than trail runners and many hiking shoes, less ideal for those prioritizing speed or ultralight goals
- Thin laces come untied frequently and feel fragile
A heavy-duty, waterproof hiking shoe built for technical terrain with aggressive traction and gore-tex surround breathability, though heavier and narrower than some hikers prefer.
Reviewers praise
- Matrix woven upper combines durability, breathability, and abrasion resistance — addressing blowout weaknesses of the prior model
- Virtually no break-in period; fits comfortably and securely from the first wear
- Gore-Tex waterproofing performs well even in submersion and prolonged wet conditions without cooking feet in heat
Reviewers push back
- Heavier than the previous model — the durability upgrade comes with a measurable weight increase
- Traction becomes sketchy on slick or wet rocks, particularly after crossing water onto dry stone
- Side protection has soft spots; sharp lateral objects can still penetrate the upper material
“It literally feels like I've got a pair of running shoes on right now cuz they're so lightweight.”
Where reviewers split on Spire GTX: One reviewer found breathability ineffective for sweaty feet despite the surround technology, while others praised the airflow and moisture management On X Ultra 5 GTX: One reviewer found the wider toe box an unqualified improvement; another noted it may require tighter lacing for narrower feet to feel locked in
