ANTI-SLIP & FITS MOST SHOES - [Women 12-14/Men 10-14] The perfect U-shape design provides a snug fit in shoes with strong adhesive, ensuring that the adjuable height increase inserts won't move around or cause crowding inside your shoes. The women shoe lifts for uneven leg are perfect for formal shoes, boots, sneakers, canvas shoes, and others. [For a Long-span Using, Please Do Not Wet the Adhesive of the Heel Lift Inserts]. TRULY CUSTOMIZABLE - Unlike assembled shoe lift inserts that are hard to separate, our heel lift inserts are shipped unassembled and come with 6 packs of extra adhesive tape, which allows you to customize the height and replace them with the shoes easily. The shoe lifts for shoes can also be trimmed to fit your shoes perfectly, ensuring that they fit comfortably and securely.
