At SurfEdge Physiotherapy, we understand that many of you rely on your trusty running shoes, whether you’re hitting the gym or hitting the trails. But how do you know when it's time to invest in a new pair? In this blog post, we’ll highlight the key signs that indicate your shoes might be due for replacement.
The Lifespan of Athletic Footwear
Running shoes are specifically designed to wear out over time due to the materials used, particularly the midsole, often made from ethylene vinyl acetate (EVA). This material balances cushioning and support, but it does degrade with use. Generally, running shoes have a lifespan of about 600-800 kilometers. Factors like your running mechanics, weight, and foot strike can all affect how long your shoes last.
Identifying Wear Patterns
The outer sole of your shoe, usually made from durable rubber, shows wear patterns that can reveal your running style. If you notice that you’ve worn through the outer sole and into the midsole, it’s definitely time for a replacement.
Understanding Your Foot Strike
Your foot strike pattern—whether you’re a forefoot or heel striker—will influence how your shoes wear. Forefoot strikers often wear out the front of their shoes faster, while heel strikers may notice more wear in the rear section. Knowing your foot strike can help you choose the right shoe for your style.
Pronation and Supination
Both pronation (inward rolling) and supination (outward rolling) are normal parts of running. However, excessive motion can lead to uneven shoe wear. A simple test: place your shoes on a flat surface. If they tilt to one side, it may indicate uneven wear and potential replacement is due.
Shoe Type Matters
Different shoes are designed for different purposes. Racing shoes, for instance, are not built for high mileage and will wear out faster than traditional running shoes. Cross trainers, on the other hand, are heavier and bulkier, which may make them last longer but can also make them uncomfortable for long-distance running.
