Running is more than just a sport or a pastime: it is a passion, a moment we dedicate to ourselves. Running is good because it allows us to relax, but it also keeps us healthy and fit. What many people ignore is that, like any sport, running requires specific “equipment.” While running, the key accessory is shoes: there are running shoes and shoes unsuitable for running.
Running (or running) shoes are divided into 8 well-defined categories, the differences of which are found in terms of the type of training, weight of the runner.
Category A0: minimalist shoe Category A0 running shoes are also known as “minimalist” shoes; they are shoes characterized by a weight between 200 and 300 grams, especially suitable for runners who perform rapid repetitions during training. The nickname “minimalist” is due to the fact that every superfluous element has been removed from these shoes. Their differential never exceeds one centimeter in height. A0s are comfortable and perfect for fast runners but, beware, they fatigue the leg in the long run (mainly due to the lack of shock absorbers).
A1 category: superlight shoe A1 shoes are the so-called superlight shoes: the weight does not exceed 250 grams. They are especially indicated for experienced and capable runners, those who perform numerous races habitually. They do not have cushioning systems but are still ideal for fast running because they promote the runner’s snappy stride and responsiveness. Main drawback: if you suffer from poor posture and if you weigh more than 70 kg, these running shoes are not for you.
Category A2: intermediate shoe Category A2 is a very lightweight shoe, sometimes reaching 300 grams. The somewhat higher (but still small) weight is due to the fact that these running shoes are cushioned, as opposed to A1, and have some support. They are great for those who want some stability and security while running, but still want to sprint and be able to be fast. They are very technical shoes, not for beginners.
Category A3: neutral shoe A3 Running Shoes are also called “neutral” shoes. They are the shoes with strong cushioning, so they are ideal for a large segment of the running population. In fact, beginners and more insecure runners may find these shoes smooth and comfortable. They weigh 300 to 400 grams. They are hardly suitable for competitive or competitive runners, but they are the perfect shoes for those who want to run for pleasure and do not give up comfort; suitable up to 80 kg in weight.
Category A4: stable shoe This category of shoes includes a series of stable models, comparable in weight to A3, suitable for those who no control their feet well during training. They have specific supports to avoid falling into over-pronation of the foot (excessive load on the inside). They are also the most suitable shoes for runners weighing more than 80 kg.
Category A5: trail shoe These shoes are a category whose weight ranges from about 300 to 400 grams. They are definitely sturdy models that protect the runner’s foot; their function is to protect the foot in non-road terrain, that is, not paved. If you run on rough and unpaved soils, the A5 category is for you. Performance in terms of output and speed gives way to foot safety. Typically, these shoes are designed to withstand grass, mud, stones and rocks.
A6 category: jogging shoe The A6 category of shoes are the jogging shoes: they are sufficiently able to adjust the cushioning of the running foot on the ground, but they are not suitable for experienced and competitive runners. They are comfortable and suitable for flat, non-gravel roads. They are suitable for anyone who runs not daily, but once in a while.
Category A7: spiked shoe Spiked shoes – category A7 – are very light, usually under 200 g. They are designed for competitive runners or those who run on the track and not on asphalt or terrain. They are the shoes used by lightweight athletes. These shoes are not cushioned and have cleats that increase the grip of the foot with the racing surface.
