Ultra-Slim 3/4 Length Design: This design prevents the insoles from crowding your toes, making them suitable for high heels, slings, open-toe shoes, dress shoes, and casual footwear. Energizing Gel: The gel in the insole absorbs shock in the heel and cushions the sensitive ball of the foot, providing relief and enhancing comfort. Fashionable and Stylish: The discreet clear gel design ensures the insoles blend seamlessly with your footwear, adding a touch of style without being noticeable.
