Shoe Life & Rotation Planner
Turn weekly trail mileage, abrasive terrain and rotation size into a replacement planning range.
PLANNING RANGE12–20 weeks
Inspect grip, cushioning and upper hold; mileage is a planning signal, not a warranty.
What changes trail-shoe life
Rock abrasion, mud, runner mechanics, outsole compound, midsole foam and rotation all matter. One pair can lose technical grip while remaining useful on easy dry trails.
The result is deliberately a range, not a warranty. Inspect outsole rounding, uneven compression, upper hold and how the shoe behaves on its intended terrain.
