【WALKHERO HEAVY DUTY PAIN RELIEF INSOLES】Designed for men and women over 220 lbs, tall individuals, or those with wide feet, these insoles have a contoured biomechanical shape that cradles the arch and heel. They enhance stability and reduce excess stress on feet, ankles, joints, and tendons. This effectively prevents injuries such as plantar fasciitis, flat feet, overpronation, and supination, all of which are caused by excessive pressure. 【Rigid Orthotic Arch Support Shell】Crafted from lightweight, high-strength polyamide, these shells provide rigid arch support with flexibility, ensuring comfort and stability. They withstand long hours and heavy pressure without losing shape, relieving pressure on feet, ankles, knees, and back for those with larger body sizes who stand or walk for extended periods. 【Comfortable Cushioning for Shock Absorption】The insoles feature 1.5mm high-resilience Foam cushioning in the forefoot and durable full-length 3mm high-density EVA, effectively absorbing shock and pressure. This design provides relief from muscle fatigue and soreness, especially for those carrying extra weight, who often experience increased pressure on their feet. This enhancement in comfort and support improves performance in various activities. 【From Fit to Comfortable】Our insoles are designed to perfectly match standard shoe sizes and come in 12 sizes—more than most other brands. Each pair features contoured biomechanical shape precisely customized to fit various foot sizes and shapes, from heel to toe, delivering optimal comfort, superior support, and improved alignment for all-day relief. 【Scientific Wearing - From Fit to Comfort】Initially, some people may feel pressure on their feet as they adjust to the arch support. To ensure a comfortable transition, We recommend wearing them for 2-3 hours a day for 1-2 weeks, gradually increasing the time to allow your feet to adjust.
