SILICONE GEL HEEL SUPPORT - YogaMedic heel spur insoles are made of soft gel. This material is slightly harder than Soft Gel silicone. Of course, these heel pads also offer maximum comfort and are 100% skin-friendly. SUPPORTS THE HEEL SPINE - Thanks to the soft material, the heel is gently cushioned with every impact and thus ensures an even distribution of pressure throughout the foot - This allows you to walk comfortably and reduce pain. VARIOUS SIZES TO CHOOSE FROM - Every foot is different, which is why you won't find a universal size with us. Choose the size that suits you from our "size choice" photo. IDEAL AND REUSABLE HOLD - The self-adhesive technique offers strong adhesive power and a secure hold on shoes. In addition, the insoles are reusable as desired - simply wash them quickly and let them dry.
