Treadmill is a routine fitness equipment in family and gym, the simplest one in today's family fitness equipment, and the best choice for family fitness equipment. Many people have treadmills at home and run barefoot. The vibration of the treadmill will cause unnecessary damage to the joints of the legs, and the soles of the feet will sweat and slip easily; Wearing a pair of thick socks can play a certain role in shock absorption, but socks, after all, have no elasticity of sports soles and cannot replace the role of sports shoes. So you'd better wear a pair of running shoes when you exercise on the treadmill. Running shoes are lighter than ordinary shoes and have softer soles, so they are suitable for use on treadmills. If not, ordinary sports shoes are ok, but choose something light and not too thick.
