Compatibility: These Endoto insoles are designed to be compatible with UGG shoes, and they also work well with a wide variety of other shoes and slippers. Choose the size that matches your shoe size; for half sizes, select the smaller half (e.g., choose W9 insoles for W9.5 shoes). 15MM Natural Sheepskin: It traps body heat, helping reduce heat loss and providing exceptional warmth. The soft wool texture cushions the feet, enhancing comfort and reducing fatigue, thus making it ideal for long-standing people. Additionally, it keeps feet dry and fresh. Enhanced Design: We incorporate high-density foam for superior cushioning and impact absorption, along with an EVA half-split for added support and shape retention. This design prevents the insoles from curling or slipping inside the shoe. Fine Craftsmanship: Each pair of our sheepskin insoles is meticulously hand-trimmed and sanded to ensure neatly aligned edges and a smoother wool surface. This attention to detail enhances both the quality and the fit, making them a superior choice for comfort. Dedicated Customer Service: Let our insoles renew your shoes and comfort every step! We are committed to delivering the best experience and continually innovate to meet diverse footcare needs. If you have any concerns, don't hesitate to reach out to us.
