Judging from the quality you care about, if it is clothes that allow exercise, such as ski clothes, mountaineering clothes, mountaineering underwear, fitness tights, etc. , feel good quality, ensure the basic performance and durability, comfort may be average. Generally speaking, it is really cost-effective, but if I choose a tights that will last for a year or more, I may not choose Decathlon.
Clothes containing cotton, such as Decathlon's clothes, are generally resistant to deformation. If they don't contain polyester fiber or spandex, the clothes will be deformed after a period of time. Basic clothes without cotton will harden if worn for a long time. It is recommended to buy high-end clothes. Hot stamping patterns may fade and fall off after a long time of wearing and washing (maybe I wear a little too much). Generally speaking, the use time of close-fitting clothes is within one year, and Decathlon's clothes are still recommended.
Decathlon's shoes are generally more comfortable, but it also depends on what kind of shoes you choose, because Decathlon's shoes are also divided into different sports, basketball shoes, football shoes, running shoes, hiking shoes, walking shoes, skateboarding shoes and so on. Choose shoes that suit your exercise, and you will have the greatest comfort.
It is not recommended to wear sports shoes as ordinary shoes. Sports shoes should be specially designed for shoes. Otherwise, after a long time, shoes will be worn or damaged due to improper use. Actually, it's not about the quality of shoes.
Generally speaking, Decathlon's goods are reasonable or even low in price, with good cost performance, but once again, you get what you pay for.
