What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Vibram XS Trek outsole delivers strong traction on rocky, muddy, and loose terrain across all reviewer accounts
- Gore-Tex Surround technology with midsole aeration channels provides meaningful breathability for a waterproof shoe
- Reinforced PU toe cap and heel counter offer solid protection from rock strikes and debris
Reviewers push back
- Narrow toe box causes toe compression on wider feet, even when sized up
- Thin laces feel fragile under hard tension and come untied frequently even when double-knotted
- Notable heel-to-toe drop is a drawback for hikers who prefer a flatter, more natural platform
A capable day-hiking shoe with outstanding Vibram traction and Gore-Tex waterproofing, held back by a narrow fit and lace durability concerns.
Reviewers praise
- Very lightweight for a waterproof mid boot, under twenty ounces per shoe in most sizes
- Gore-Tex membrane keeps feet dry without seepage in wet conditions
- Contagrip sole compound and advanced chassis system provide exceptional traction and lateral stability on mixed terrain
Reviewers push back
- Uppers prone to blowouts at toe cap and along pinkie side after high mileage
- Advanced chassis causes arch pain in some users, particularly those with wide feet
- Limited protection through the ball of the foot compared to beefier boots
Reviewers agree the X Ultra 4 GTX is a lightweight, stable hiking shoe with excellent traction and waterproofing, though some note durability concerns and a narrower fit that may cause arch discomfort.
