1. Your legs are aching

If suddenly there is pain in the knees, hips, lower leg, then it means that your sneakers no longer provide the legs with the necessary support.


2. Worn outsole

If you notice that the protectors are worn out, then it's time to change your shoes. You can slip and get injured, because it is the protectors that are responsible for the adhesion to the surface.


3. This pair of shoes with you for a long time

Shoes should be replaced if you ran in it from 500 to 1,000 km or 45-60 hours played basketball, tennis or practiced dance aerobics. Your sneakers will live longer if you alternate different pairs. Studies show that alternately run in two pairs of shoes will be as long as in the three, used in turn.

4. Consider your weight

If you weigh a little, you can run and 750 km in some sneakers without the risk of harming yourself. If your weight exceeds 90 kg, the "mileage" of your shoes can be reduced to 500 km.

5. They do not pass the torsion test

Take the sneaker from both ends and twist in opposite directions. Do you feel good resistance? If the shoes rotate without much effort, then it's time to go to the store for a new pair.

6. Check the material in the middle of the foot

Use your thumb to press the middle part of the sole. If this place is solid and not pushed (and not soft and springy), then it's time to think about a new pair of shoes.

7. Check the shoes for symmetry

If the heel of sneaker "moved on side" or the outsole has worn out, change your shoes. Also throw it away if the sneakers on a flat surface do not stand straight.

8. The corns began to appear

If you notice that the toes are protruding forward, pulling heavily on the fabric, or calluses appear, it means that your sneakers inside have worn out, despite the fact that their appearance can be very good.
