What should be a pair of good sports shoes?

1. Internal support characteristics The multi-directional movement in aerobic exercise requires the shoes to be very stable. Each manufacturer provides different internal support characteristics. Some manufacturers use a molded midsole so that the foot can step on the shoe properly. In addition, the fibers along the shoe can also provide support. Some manufacturers only add fiberboard to the heel to increase the flexibility of the shoe.
2, the external support of a strong wear heel support sheet can greatly reduce the heel movement. The wider part on the outsole is called the heel fixation bar. It is made of plastic and is distributed along the foot and fixed on the heel support. Many shoes now use a fixed frame, which is a polymeric attachment used to support the state, and is longitudinally distributed along the exterior of the shoe. Other stabilizing features include plastic support strips (usually attached to the eye of the shoe), Velcro sticking and sticking strips, and mid-segment support.
3, cushioning characteristics The conventional impact of aerobic exercise produces special pressure, generally equivalent to 5 times your weight. Therefore, good cushioning performance is a must. The midsole will help disperse this impact. A good midsole is made of molded EVA or polyurethane. Various manufacturers have introduced a variety of technologies to further increase the cushioning performance of the midsole. If you are down-sloping or performing strenuous exercise, you may need better cushioning than someone who is leaning too far downwards.
4, replaceable insoles insole also has a certain cushioning performance, while the most vulnerable to damage. To replace the insole during half of the life of the shoe, there is a basic replacement principle: after 150 hours of aerobic exercise, the insole will lose its elasticity, and the insole should be replaced at this time. (According to different people, different training may be.)
5, the flexibility of elastic shoes is determined by the feeling of your feet when exercising. Only cushioned fiberboards in the heel have better flexibility than sports shoes with integrated fiberboard designs, and low-top sports shoes can also improve flexibility.
6. Fit Your Feet Your feet will increase when under pressure and during aerobic exercise. The heat generated by intense exercise will increase the size of the foot by half. At the same time, when buying shoes, you should not squeeze your feet too much. There should be a gap between the top of your shoes and your longest toe to ensure that your toes can move freely and the heel area should be properly placed. In addition, the length of the foot should be measured frequently because both age and damage can change the size of the foot.
