An insole is a cushioned layer placed inside a shoe to provide comfort and support for the foot. It helps absorb shock while walking or running, making each step feel softer. Insoles can also help improve the fit of shoes, preventing slipping and reducing pressure on certain areas of the foot. Many people choose to use custom insoles, especially those with foot problems like flat feet or plantar fasciitis. These specialized insoles are designed to provide extra support and alignment, helping to alleviate pain and improve overall foot health. Whether for sports or everyday wear, insoles play a crucial role in foot comfort.
