What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Anatomically shaped, wide toe box gives toes genuine room without sacrificing midfoot and heel lockdown
- Zip foam midsole delivers a balanced mix of cushioning, ground feel, and rebound that beds in well over miles
- Rocker geometry makes the ride efficient and easy underfoot on pack single track and gravel
Reviewers push back
- Shallow 4 mm lugs limit traction on loose, muddy, or genuinely technical terrain — not a deep-mountain shoe
- Wide fit can feel insecure for narrow-footed runners, requiring aggressive lace tension to achieve lockdown
- On steep technical descents the foot can shift forward, causing toe bump — the shoe is out of its element there
A well-built, roomy-toed trail shoe with capable cushioning and grip for mild to moderate terrain, though it falls short on technical descents and very aggressive ground.
On Ultraventure 4: Sizing read: one reviewer found the shoe runs slightly short and considered sizing up, while others call it true to size across the board
