Running in worn-out shoes can cause a number of issues, ultimately leading to future injury woes. SportsShoes explains when and why you should replace your running shoes and how many miles you can expect from each pair.
Monitor the condition of your shoes on a regular basis. There will be noticeable signs of wear after considerable use and any damage usually becomes visible at pressure points e.g parts of the shoe that take the most impact, especially the outsole and uppers - where your shoe bends and stretches as you run. The grip and tread on your shoes will likely deteriorate the most, and this might happen more on one side of the sole than the other, depending on what kind of runner you are (see below).
Track the mileage of your shoes by using a platform like Strava. Use a laptop* or computer to access your account, you can add your running shoe/s to your personal equipment list via the SETTINGS menu and MY GEAR. Each time you complete a run, select the shoes you have used for that particular activity and the mileage will be automatically recorded and added to a cumulative total. When adding new shoes to your Strava account, don’t forget to set a notification e.g. 500 miles to remind you exactly when your shoes will need to be replaced.
*Please note that this action cannot be performed via the mobile Strava app.
Over time materials inevitably start to weaken. Foam will lose cushioning and glue may lose its bond and begin to crumble. And remember that damage to shoes is not always clearly visible. Generally, 300 miles is the minimum you should expect from a shoe and 500 miles is the maximum. After this, you should look at replacing your shoes with a new pair.
Look after your shoes and treat them with respect, no shoe is indestructible or designed to last forever. Simple things like loosening and untying shoes after use means that you don’t have to force or struggle to get them on your feet the next time you wear them. Using a shoe horn to put them on also protects and prevents damage to the back of the heel. Regularly clean your shoes, but never machine wash or tumble dry. By doing so, you can compromise the materials, causing them to shrink and damage the stitching and glue that bond the materials together. Instead, allow your shoes to dry naturally after a run and then gently clean when dry with a hard brush. If they are particularly dirty after a trail or fell run, wash and brush under a cold water tap and again allow to dry naturally, remembering to keep them a safe distance away from a radiator or heat source. Stuffing your shoes with old newspaper after cleaning will speed up the drying process and help your shoes to keep their shape. As well as soaking up moisture, this method can also help to reduce odour.
A majority of running injuries are caused by the repetition of something very minor happening 1000’s of times over the course of a run. This could be caused by more impact getting through the shoe and into your lower limbs, due to the shoe being worn out or not good enough in the first place, or a lack of support allowing your foot to over-pronate on each foot strike, which will drop your ankle then knee and hip out of alignment, leaving you more susceptible to problems. The right running shoe can help avoid these kinds of problems, a worn-out shoe can leave you open to problems.
There are a number of different ways in which you can reuse or dispose of your old shoes. The first of which is to get creative and repurpose them – why not consider using them outside as a plant pot, herb garden or even as a bird-house? Click here for more inventive ideas.
If your shoes still have plenty of life left in them, we recommend giving them to charity, or better still, donating to ReRun Clothing, a community interest company aimed at prolonging the life of running clothes and equipment, founded and run by Team GB ultra-runner Dan Lawson and his wife and family Charlotte, Lilly and Ruby.
Recycling shoes and clothing will become a much easier task as we look towards a greener future. Retailers and brands worldwide are now moving towards a more sustainable and environmentally friendly approach, creating clothing and equipment from ethically sourced and in most cases, fully recyclable materials.
Will a more expensive shoe last longer? The answer is not really, as the cushioning in most road running shoes is good for about 300-500 miles. A more expensive shoe will just give you better cushioning/protection over those miles than a mid/entry level shoe. Whilst 500 miles sounds a lot, an average of 20 miles per week only gives you roughly 6 months of shoe life. The difficult part, unless you keep a mileage log, is knowing when a shoe is worn out and ready to be replaced. At 500 miles they can still look fine, but it is just the midsole where the cushioning sits that deteriorates, the upper and sole can still look like new. A common complaint from running in worn-out shoes is aching knees or hips, if you have not upped your mileage, but you are starting to feel pain in your knees, then it may be time for a new pair.
