Enter your average distance run per session, how many times per week you use them, and the date you started using them. The calculator will estimate your running total and tell you how it compares to the general replacement recommendation (500-800 km). Running apps like Strava, Garmin Connect, etc., also often have features for tracking mileage per pair of shoes.<\/span><\/p>\n<h3><b>Why is it important to replace your running shoes?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The main reason is <\/span><b>prevent injuries<\/b><span style=\"font-weight: 400;\">The midsole of your running shoes, responsible for cushioning and support, degrades with repeated use and impact. Running in worn-out shoes increases the strain on your joints (ankles, knees, hips) and soft tissues, increasing your risk of overuse injuries such as tendonitis, plantar fasciitis, or shin splints.<\/span><\/p>\n<h3><b>How many kilometers do running shoes really last?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The general recommendation is to replace them every <\/span><b>500 to 800 kilometers (about 300-500 miles)<\/b><span style=\"font-weight: 400;\">.

The <\/span><b>time<\/b><span style=\"font-weight: 400;\"> It also plays a role. Even if you don&#039;t run much, the midsole materials can slowly degrade over time (oxidation, temperature changes). Therefore, even if they have low mileage, it&#039;s not recommended to use shoes that are very old (more than 2-3 years old, even if they&#039;re unused).<\/span><\/p>\n<h3><b>How can I visually tell if my shoes are worn?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Look for these signs:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Sole:<\/b><span style=\"font-weight: 400;\"> Very smooth or irregularly worn areas.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Midsole:<\/b><span style=\"font-weight: 400;\"> Deep, permanent wrinkles (compression signs), feels much harder to press than when new.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Heel (heel counter):<\/b><span style=\"font-weight: 400;\"> Deformed or no longer holding the foot properly.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Upper (upper mesh):<\/b><span style=\"font-weight: 400;\"> Tears or holes (although this affects the main function less).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Comparison:<\/b><span style=\"font-weight: 400;\"> If you have a new pair of the same model, compare the feel and height of the midsole.<\/span><\/li>\n<\/ul>\n<h3><b>Does this calculator work for walking, trail running, or other sports shoes?<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Walk:<\/b><span style=\"font-weight: 400;\"> The mileage concept applies, but since the impact is lower, walking shoes typically last longer (maybe 800-1000 km or more).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Trail Running:<\/b><span style=\"font-weight: 400;\"> Mileage also matters, but sole (lug) wear and upper durability on uneven terrain are equally important factors. The lifespan may be similar to or slightly shorter than that of asphalt if the terrain is very technical.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Other Sports (Basketball, Tennis):<\/b><span style=\"font-weight: 400;\"> Wear varies (more lateral movement, braking). It&#039;s not usually measured by mileage, but rather by time of use, loss of sole grip, or deterioration of lateral support.<\/span><\/li>\n<\/ul>\n<h3><b>Is it advisable to rotate between several pairs of shoes?<\/b><\/h3>\n<p><b>Yes, it is highly recommended.<\/b><span style=\"font-weight: 400;\"> If you run frequently, rotating between two or more pairs allows the midsole foam to decompress and recover some of its properties between uses (usually within 24-48 hours). This can slightly extend the lifespan of each pair, and slightly varying the stimulation your feet receive can help prevent injuries.<\/span><\/p>\n<h3><b>Does the brand or price of the shoes greatly affect their durability?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Not necessarily directly. More expensive sneakers may use premium materials that <\/span><i><span style=\"font-weight: 400;\">potentially<\/span><\/i><span style=\"font-weight: 400;\"> They may last longer or degrade more slowly, but this isn&#039;t always the case. Very light or racing shoes, although expensive, tend to have less durability than everyday training shoes. The most important thing is to choose a shoe that&#039;s appropriate for your stride, weight, and type of use, and replace it when appropriate, regardless of the price.<\/span><\/p>\n<h3><b>What physical signs indicate that I need to replace my shoes URGENTLY?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The clearest sign is the appearance of <\/span><b>new aches or pains<\/b><span style=\"font-weight: 400;\"> (in your feet, ankles, shins, knees) that you didn&#039;t have before with those same shoes and that can&#039;t be explained by a change in your training.
