Insoles can help relieve pain, redistribute pressure, and correct any malalignment in the leg due to different types of flat feet. However, because of the sheer number of insoles on the market, making a choice can be overwhelming. To help, we’ve narrowed down the list to include only the best types of insoles for flat feet.

What Causes Flat Feet?

Flat feet, or flatfoot, is a condition marked by the absence of arches in one or both feet. This means that when standing, the foot's pads make direct contact with the ground, and the arch is not visibly present unless the foot is lifted.

While all babies are born with flat feet, arches typically develop by age six. However, approximately two out of 10 children continue to have flat feet into adulthood, a condition sometimes referred to as fallen arches.

Note: While flat feet are generally not problematic for most individuals, those experiencing pain or other issues can explore various treatments, including high-quality supportive insoles, to address the condition and enhance foot biomechanics.

  • Deep heel cup: Insoles with deep heel cups benefit individuals with flat feet, as they provide stability, reduce overpronation, and alleviate heel pain. They can also enhance standing balance.
  • Durable materials: Choose insoles made of durable materials like EVA, polyurethane, cork, rubber, foam, or gel to ensure they can withstand daily wear and tear. They will prevent the need for frequent replacements.
