Footwear Replacement Schedule And Mileage Estimates

Long-distance hiking places continuous demands on footwear. Over time, midsoles compress and lose resilience, outsoles wear down and provide less traction, and uppers may stretch or tear. Even when shoes remain physically intact, their support and cushioning characteristics can change significantly.

Mileage estimates for footwear longevity vary widely and depend on factors such as terrain roughness, hiker weight, pack load, and walking style. Some hikers observe that shoes remain comfortable for a limited range of hundreds of kilometers or miles before subtle discomfort appears, while others continue using them longer when conditions are less demanding.

Rather than relying solely on fixed mileage numbers, many hikers monitor specific signs of wear. These include flattened midsoles leading to increased foot fatigue, noticeably reduced grip on slopes, or persistent new pressure points as uppers lose shape. When such signs accumulate, the likelihood of discomfort or injury can increase.

Planning for replacements involves identifying towns or resupply points where new footwear can be purchased or mailed ahead. Shipping pairs to known destinations, allowing for variable hiking pace and possible delays, helps ensure availability when needed.

Being attentive to changes in how feet and legs feel in existing footwear provides practical guidance. Early replacement, while potentially adding cost, may prevent overuse problems that could interrupt a thru hike.
