CUSTOMER ARE OUR PRIORITY: We offer 100% no risk money-back guarantee if you're not thrilled with your purchase for any reason. Ailaka provide free exchange policy if size is not suitable. Just tell us and we will do our best to give you the most satisfactory solution. HUMANIZED DESIGN: Ergonomically designed, inner insoles render the best cushion ever, and prevent injuries resulting from wrong feet support. They are ideal for all your UGG boots, work boots, wide-fitting lace-up shoes, sports shoes, tennis and golf shoes. PERFECT WORKMANSHIP: Tightly stitched to the sheepskin, the wool felt layer and pigskin adheres firmly to the soles. The fleece will not come off and leave lint on your socks. Thick and fluffy fleece with high-density felt keep the insoles from going flat as pancakes even though it has used for many times. ANTI-SLIP & BREATHABLE: The bottom layer made from pigskin can keep insoles in position and will not ruck up or move around inside your boots or slippers. It could absorb the moisture produced by the feet and neutralize odors. WARMTH & COMFORT: With 2.5 cm thick 100% premium quality sheepskin material, the wool women’s insoles offer gorgeous comfort and warmth to your feet whether in cold winter or rainy days. Relief pressure and pain from shoes.
