First, we need to look at the thickness of the insole. Generally, the insole made of cloth or fiber should not be too thin. If it is too thin, the insole will be uncomfortable inside the shoes, unless the shoes are smaller.

Next, it depends on whether the sweat is absorbed and what the main ingredients are. Generally, the cloth shoe pad needs to be changed frequently, which mainly depends on the cloth to absorb sweat;
What we need to see in the heel is the hardness of the insole. If the insole is too soft, it is easy to wrinkle, leading to a retraction of the insole, which finally makes your feet unbearable.
But the insole should not be too hard. Too hard will cause pain in the soles of the feet. Over time, thick calluses will grow on the soles of the feet. In the future, as long as you buy a hard insole, your feet will be painful.
Therefore, choose a soft and hard and moderate insole.
Finally, look at the process of the insole. The soft and hard soles are easy to wrinkle, leading to the shrinkage of the insole. Finally, you don't need it. But don't have it. Too hard feet are often used, and the foot plate will grow thick after rubbing. If you want to use it later, the foot pads will be painful, and you will quickly choose to use both soft and hard and moderate.
