Hello. First of all, when it comes to running shoes, nike free belongs to barefoot running shoes. Nike free 3.0, which is a running shoe suitable for sprinters to wear during training, imitates barefoot sports, makes runners feel as relaxed as without shoes, and helps to exercise calf muscles; However, the sole of nike free 3.0 is too soft and has almost no shock absorption function, so it is not suitable for wearing for a long time, so this nike free long-distance running is not suitable; Nike free 5.0 has light weight and good foot feeling, which can correct running posture and strengthen foot strength. However, due to the weak shock absorption effect of heel, the protective effect of shoes on feet is limited. This is an unconventional running shoe, which is suitable for middle-distance sprinters. Therefore, this Nike free long-distance running is also inappropriate; Nike free 7.0, this shoe has light weight, good flexibility and good wrapping. Although it is not wear-resistant in the case of long-term exercise, it is still suitable for long-distance running enthusiasts to train and wear, so this nike free long-distance running is suitable; Finally, let's talk about the FREE daily launched by Nike on a free basis. The breathable mesh and synthetic material of the upper provide the greatest support, while the heel brings the greatest comfort. The midsole and heel provide good elastic cushioning, and the outsole is made of wear-resistant BRS 1000 rubber, so you don't have to worry about wearing it even if you exercise for a long time, so this shoe is more suitable for long-distance running. In short, nike free series is only suitable for professional runners (because its overall shock absorption effect is not really ideal), and it is not suitable for ordinary runners to lose weight. It is very important to choose running shoes that really suit you. The premise is to really understand your actual foot type (high arch foot, low arch foot, eversion, eversion, normal), and query the running shoes that Baidu knows should be chosen.
