I don’t want to put pressure on anyone, but there are 24 days left until the Valencia Trinidad Alfonso Zurich 2025 Marathon. It is, probably, the most important event of the year for marathoners on the national scene. Valencia has become a reference inside and outside our borders for the most advanced runners. But it has also become the perfect showcase to continue gaining followers in a world where groups of runners for all levels multiply, specialty coffee shops with running clubs and, phone in handthe new followers of a religion that seems not to reach its ceiling. New faithful who are bombarded with new training plans, with the benefits of the Norwegian methodclothing brands that have understood the concept with a clear turn towards design and fashion or with YouTube channels in which the latest shoe, the latest revolutionary foam and the most complex carbon plate are analyzed. And among numbers that already exceed three figures, the next generation GPS watch and the t-shirt that weighs 35 grams, sometimes we forget that running, which is running, is run with our feet. And what we wear is key to avoiding injuries. This is what Marta Molina, a doctor in traumatology, maintains, who in statements to ABC warns: we must change shoes every 700 kilometers. A big “it depends” “Each runner has different biomechanics. Detecting imbalances or poor support technique can prevent future injuries (…) The most frequent injuries that we see in consultation during these weeks (prior to the Valencian appointment) are Achilles tendinopathies, overloads in calves, plantar fasciitis or discomfort in the knee and hip derived from excessive training or inappropriate footwear” As a runner with a decade under my belt, I will say that I have gone through each and every one of those concepts at some point. In the form of injuries or discomfort, but I have not missed any of those diagnoses along the way. And what’s worse, I have the feeling that most of those who start in this sport go through some type of discomfort of this type. It shouldn’t be like this but usually we don’t realize the mistake until we have hit the wall. Molina talks about inappropriate footwear and change it after 700 kilometers. And yes, it is a common problem. Either for investing little initial money or for wanting to stretch the gum of a product (that of running shoes) whose RRP has settled above 150 euros in a good part of the market. Dani Navarro, a worker at Bikilaone of the most renowned stores in the country. “Our feedback from customers is that training shoes usually last between 700 and 900 kilometers. There can always be exceptions due to pure biomechanics, runners who do not reach that mileage or who, due to having a very refined technique, far exceed them.” In Runneaa media specialized in this sport, echoed a study in which they pointed out that training shoes began to lose part of their properties and effectiveness after 400 kilometers but that runners did not perceive the decrease in performance until 640 kilometers. The problem is that the first warning is usually discomfort. Navarro also points out two important details. The first thing is that it talks about “training shoes”. The second thing is that it puts the focus on the foams. “The mileage could be extended a little if the shoes are rotated, especially for those who run daily. This way the materials don’t wear out as much and they don’t crush the materials as much.” These two points are key, especially with the arrival of the new foams that offer a much softer and more reactive touch but whose useful life is also in question. The so-called “training shoes” are recommended for people who are starting out in sports because they are the ones that protect the muscles the most and are the most comfortable for going at slow paces. They are also used by experienced runners when they want to accumulate kilometers in preparation. The lower the weight and the better the technique, the more kilometers you can get out of the shoes. The catalog is very wide and varied, from the classic Saucony Triumph or Brooks Glycerin with a slightly firmer feel to the ubiquitous and very soft Nike Invincible, which have earned a place in hearts for their endless padding. But both Molina and Navarro agree on the same point: exceed mileage of shoes increases the risk of injury. The shoe is more likely to become more unstable and the joints and muscles will face a greater challenge. In addition, you have to take into account what you buy and why. Navarro remembers that there are “mixed sneakers” designed to run a little faster, face training plans with series or changes of pace (the famous fartleck). These shoes are predicted to have an average useful life of about 600 kilometers. Sneakers among which we find classics such as the Adidas Adizero Boston, the legendary Nike Pegasus or the more modern New Balance Fuelcell Rebel. At the higher end in price and muscular demand are “competition shoes”, items designed to perform to the maximum of our possibilities but with a very short useful life “of 300 or 400 kilometers” estimates the Bikila expert. The maximum representative of this last option were the Adidas Adizero Pro EVOsneakers weighing 138 grams with which Tigst Assefa breaks the women’s marathon world record and that the German company itself warned of a useful life of a single competition and the prior filming for the adaptation of the runner. Starting price: 500 euros and limited units. A category that was previously dominated by aggressive flyers with half-toe midsole and where now foams of wild sizes reign and carbon plates, a new trend that was inaugurated by the Nike Vaporfly and that competitors have replicated with the Adidas Adizero Adios Pro, the Saucony Endorphin Elite or the most striking Hoka Cielo X or the galactic Puma Fast R Nitro Elite. … Read more
