How settled the rating is against every other rated shoe. A shoe can rate high on confidence with relatively few reviews of its own when its product line has a long record and external ratings from retailer sites agree. Confidence is low when we have few ratings or when runners disagree.

External retailer ratings
We break apart ratings from mass-market retailers and specialty running shops since they serve different audiences.
The middle of the bar marks the typical shoe at each type of retailer. The dot shows where this shoe ranks in comparison.
Based on
Each rating combines our runners’ ratings, the brand’s track record, and external ratings. This shoe has no earlier versions, so we start from how the brand’s other shoes rate. As more of our runners rate a shoe, their ratings carry more of the weight. The bars show roughly how much each source contributes.

Pros
- Reviewers describe a bouncy, springy ride at any pace.
- At 8.7 oz it is light for a 50mm stack.
- One reviewer says it still has life left at about 400 miles.
Cons
- Three reviewers warn that it is unstable, one advising runners with weak ankles away from it.
- At 50mm the stack sits well above the 40mm World Athletics limit, so it is not eligible for records in official road races.

Overall
Amazing running shoes. Very comfortable and bouncy. Much more than the usual Nike VF and AF.
Would not recommend for runners with weak ankles as these can be unstable.
Otherwise these are near perfection.

The greatest shoe ever for old runners
5/5
Overall
Even with the crazy stack height, the shoe is fairly light, and very responsive. In fact, at any pace, it feels springy. Even after about 400 miles, the shoe has life left in it. The upper locks the foot in, and never feels hot. I'm reviewing the Prime X strung and not the original.

Amazing shoe, but pricey and not much for looking at
5/5
Overall
The Prime X is an incredible shoe. It feels amazing, all 50mm of that stack are great. It is unstable, so if you have any stability issues, I'd stay away. Good for a wide range of runs.
