5 Best Altra Trail Running Shoes in 2023

How we test trail running shoes

Working with our team of wear-testers and editors here at RunRepeat, we thoroughly tested and analyzed every model on this list. In addition to our own research, we’ve also collected more useful information from other trail experts in the running shoe business, as well as extensive feedback from regular runners.

To give you an idea of how we make our final recommendations, the approach involves:

• Buying all the Altra trail shoes we test using our own funds to ensure a 100% BS-free review.
• Performing a gamut of mechanical tests inside the RunRepeat lab, which involves cutting each model into pieces and measuring 30+ parameters, from the outsole traction and durability to waterproofing and breathability, among others.
• Wear-testing each pair by logging 30-40 miles running in rugged terrains and muddy paths.
• Collecting more comparable data from other shoe experts and regular users of Altra trail running shoes.

To conclude the process, we go to our CoreScore system to make a calculation based on the aggregated data above. A final rating is shown ranging from 0-to 100 on each model, which pretty much gives us our best picks in specific areas.
