[Thorough Flatfoot Prevention with a 3-Point Arch Structure] These insoles feature a 3-point structure—an inner arch (arch support), heel cup, and metatarsal pad—to support children's feet, which are prone to flatfoot. They firmly support the arch, suppressing the progression of common childhood conditions like X-legs, O-legs, and flatfoot. These insoles guide children's soft skeletal structure into the correct position, supporting beautiful posture. Achieve balanced, fatigue-resistant feet with SunnyHug's flatfoot insoles. [Made with High-Performance PORON Material! Durable Insoles That Won't Lose Their Shape] The heel area of these children's insoles is made with "PORON," a high-density urethane with excellent shock absorption. Unlike inexpensive kids' insoles or insoles, they resist compression even with daily weight-bearing, maintaining the height necessary for flatfoot correction. These are high-performance insoles from SunnyHug, designed to protect active children's feet and legs from the impact of asphalt. Perfect for those looking for durable flatfoot insoles that last. [Recommended for Sneakers, Adjustable Size Children's Insoles] These kids' insoles can be easily cut with scissors to fit various shoes. [Caution] These products have a thick design to enhance their flatfoot correction capabilities. Therefore, they may feel tight in shoes with low insteps, such as indoor shoes or loafers. To ensure a proper fit for your child's feet, please remove the original insole before inserting these insoles.
