COLOGNE (dpa) – A German professor has harsh words for cheapskate joggers who wear worn-out, ragged shoes on their runs.
Keen joggers should buy a new pair of running shoes every year, says Ingo Froboese of the German Sport University in Cologne. “Shoes wear out after between 600 and 800 kilometres,” he says in advice that is independent of the shoe industry. If you run even more in a year, you might even need more than one pair every 12 months.
Because running shoes deform slightly during use, it’s also best to give them time to regain shape as well. That’s why it may be smart to own two pairs of shoes at the same time and use each pair alternately.
If a shoe’s sole tears, or a split appears in the sole cushion, or a hole develops in the upper, it’s time to get a new pair.
Froboese has another piece of advice for joggers: “You should always shop for your new running shoes in the evening.” Feet tend to swell up during the day. Swollen is the size they will have when you are jogging, explains Froboese.
A new pair of shoes should fit snugly and not be too large. If you are new to jogging, you should get your running style checked at a proper sports-shoe store to find the best shoe.
Froboese also thinks it’s best not to use off-the-shelf shoe inserts. “They will alter the shape of the foot and can cause problems.” Those problems could include injuries to the hips or knees, he says.
Orthopaedic shoemakers can make you tailored inserts if it is really necessary to correct your gait under medical supervision. It will quickly become apparent if you have bought the wrong pair of running shoes.
“Pain in the Achilles tendon may be an indication that your shoes are too soft,” suggests Froboese.
Where you feel as if your foot is tilting away to the side while running, expect some knee pain to develop as well: the problem is that the shoe shape is not providing the right support.
A pair of shoes should become completely comfortable after three runs, or six at the most, the prof says. If problems persist, discard the shoes and shop for a pair that are better suited to your feet.
