How long do running shoes last?

Today we would like to answer a common question many runners customers ask us when they come to buy a pair of trainers: How long do running shoes last?

It should be made clear that the useful life of your trainers depends on many factors, such as the type of shoe, quality of the cushioning, foot type, running frequency, terrain, runner's weight (running produces a force two to three times the body's weight, which affects the body when pushing off and landing), running style… 

However, here are some key facts will help you to identify if you need to buy a new shoes:

The average running shoe will last for around 1200-1500 km.

The first property of the shoe to degenerate is the cushioning. The midsole, usually made of EVA (ethylene vinyl acetate), loses about 35% of its cushioning capacity after just 500 kilometres. This fact illustrates why most running shoes also have additional, higher density, therefore longer lasting, cushioning systems within the rear of the shoe.
Over time the upper the shoe will also become distorted, therefore exaggerate any irregular biomechanics of your foot during the running gait.

The average running shoe will last for around 1200-1500 kilometres (slightly less far for heavier individuals). Consequently, if you run approximately 30 kilometres per week, you must buy new running shoes at least once a year.

Asics remembers that run long continuously subjects your body to roads, pathways and other compacted surfaces. In contrast to everyday life, this can often put great strain on the runner. That is why cushioning and support are crucial factors for the perfect shoe.
