<\/p>\nBuilt to last, running shoes have a mileage limit that must be strictly adhered to if you want to avoid unpleasant injuries.<\/p>\n
<\/p>\n
<\/p>\n
No, running shoes\u2014just like car tires, brake pads\u2026 and anything else destined to inevitably face planned obsolescence\u2014aren\u2019t eternal; they have a sort of expiration date. Sooner or later, we\u2019ve all found ourselves running in our \u201cfavorite shoes,\u201d unable to replace them despite nagging sciatic pain, attributing our declining performance to a period of stress or fatigue, work, other commitments, the weather\u2026 but very often, in fact, these are just excuses. <\/p>\n
In fact, based on expert advice, it can be argued that the relationship between a shoe’s lifespan and its type is currently as follows:<\/p>\n
A1: 150 to 300 kilometers;<\/strong><\/p>\n A2: 250 to 500 kilometers;<\/strong><\/p>\n A3\/A4: 500 to 1,000 kilometers.<\/strong><\/p>\n The 1,000 kilometers, therefore, represent the critical distance\u2014that is, the maximum mileage that can be covered while wearing a particular pair of running shoes<\/strong>. No, it doesn\u2019t matter at all if the shoe still \u201clooks\u201d good, isn\u2019t damaged, or doesn\u2019t have a particularly worn-out sole\u2026 In fact, as the kilometers add up, a running shoe loses its elasticity, risking becoming the cause of leg inflammation or sciatica\u2026<\/strong> <\/p>\n All of this has, of course, been \u201cscientifically and thoroughly\u201d tested by me personally on my sciatica, ankles, calves, knees, hips, back, neck, and shoulders\u2026<\/p>\n Upper, outsole, midsole<\/strong>. If any one of these three components wears out before reaching the so-called \u201ccritical distance,\u201d then that particular type of shoe is not suitable for the runner, who will consequently need to reconsider their choices. <\/p>\n Climate<\/strong>. The materials used to make shoes may be very durable, but they don\u2019t perform very well in terms of temperature. Polyurethane is sensitive to low temperatures, while gel is sensitive to high temperatures; for this reason, older models on sale may be riskier than models that have just hit the market. <\/p>\n Washing and drying<\/strong>. Shoes should be hand-washed in cold water and allowed to dry at room temperature, preferably in a well-ventilated area. Machine washing (even at 30 \u00b0C) is not recommended, especially if followed by drying near heat sources that are not adequately shielded. <\/p>\n Excess weight<\/strong>. An athlete’s excess weight shortens the life of the shoe by at least 20%. <\/p>\n Consequently, it\u2019s easy to see that the average lifespan of a good running shoe is about 800 kilometers, while for racing shoes, the recommendation is to replace them about every 400 kilometers<\/strong>. Running in a high-quality shoe that has lost most of its elasticity is, in fact, extremely harmful! <\/p>\n","protected":false},"excerpt":{"rendered":" Built to last, running shoes have a mileage limit that must be strictly adhered to if you want to avoid…<\/p>\n","protected":false},"author":2,"featured_media":72051,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-72050","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-senza-categoria"],"acf":[],"yoast_head":"\n
