If you mainly walk, the basic requirements for walking shoes are: the soles are elastic, which can reduce the impact of each step on the joints. In addition, the sole is easier to bend than running shoes, because the foot is more powerful when walking, the foot bends more, and the heel needs to be stable and firm, because walking is the main force to shoulder the whole body weight. If you walk often, the elastic ash in fitness shoes will run away quickly. Although it is not bad, the protective effect is not very good. If you mainly want to run, a pair of good running shoes is essential. Just because shoes are expensive doesn't mean shoes will be better. Choosing the right running shoes depends on your weight, foot type, running style and injury. Before buying shoes, try them on and run a short distance to see if they are elastic enough and fit. In addition, the sole should be easy to bend. If you grab both ends of a shoe and bend it, the biggest bending part should be at the sole of your foot, and the heel part should be suitable. If it is too big, it will make you unstable when running and easily damage your ankle. If you like aerobics, running shoes are not suitable. Because the soles of running shoes are narrow, it is easy to sprain your ankles when doing side exercises. You can choose a pair of multifunctional shoes, which can support the sole well and meet the needs of a small amount of running and jumping. Generally speaking, the temperature in the gym will remain the same all year round, and you will sweat when you exercise. It is best to choose sports shoes with good air permeability and light weight. Changing sports shoes every year is also a good way to protect joints.
