Secondly, try to choose slippers made of EVA material, with smooth uppers and easy to clean. They are waterproof, odor-resistant and lightweight. The uppers have few lines and will not easily trap dirt and evil. Finally, all slippers will age after being used for a long time, and dirt will penetrate deep into the inside of the slippers.

"Feeling like stepping on shit" slippers, beware of health risks

Soles that are too soft can reduce a person's control over their feet. It has poor stability and insufficient support, which will increase the risk of sprained feet and aggravate foot problems such as varus and valgus.

In severe cases, it will also affect the shape of the leg, causing lumbar pain, scoliosis, anterior pelvic tilt and other problems, forming a bad posture.
