The 3/4 hard support insole is designed to reduce foot and heel pain caused by plantar fasciitis, flat feet, and fallen arches. The lightweight EVA absorbs the impact of each step, distributes foot pressure, and reduces fatigue. Suitable for those standing down to earth all day and those who want to keep their feet in good health. PCSSSOLE has released a new version of the arc arch support, which is now available in Europe and the middle east. It's available for pre-order now. Insoles are not recommended for Shallow mouth shoes. Keep doing foot exercise every day after a day's work to make your foot plantar fascia work well.
