Critics & buyers
The human jury in one chapter — what the video reviewers score and say, the reviews behind it, and how Google buyers rate them.
What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Vibram Megagrip outsole with 5mm multi-directional lugs delivers trustworthy traction across wet rock, mud, roots, and dry leaves
- Secure, locked-in fit from the woven upper, gusseted tongue, and midfoot cage keeps the foot planted on technical terrain
- More durable compression-molded EVA foam is designed to hold its ride feel over longer mileage than the previous version
Reviewers push back
- Midsole is noticeably firmer than previous generations, which some reviewers found uncomfortable and even cramping on long or steep efforts
- Toe bumper protection is considered flimsy by some reviewers and insufficient for aggressive rock-kicking terrain
- Fit runs snug and can feel narrow, particularly in the toe box on long descents — half-sizing up is frequently advised
The Speedgoat 6 is a reliable, stable max-cushion trail shoe with excellent traction and a secure upper, but its firmer-than-expected midsole divides reviewers sharply.
Midsole firmness: most reviewers describe it as firm but acceptable for a classic trail shoe feel, while one reviewer found it so stiff and uncomfortable it constituted a major flaw
