- Size: One size • Three invisible heights: the half insoles are designed to be invisible, allowing you to increase your height without anyone noticing. Available in three optional heights, they are perfect for various occasions such as meetings, dates, weddings, shopping, or any event. • High-quality material: made with soft and durable medical-grade gel, these honeycomb-designed insoles are designed to absorb impacts and reduce stress on the heels with every step. They are soft yet stable, providing the necessary support for your feet. • All-day comfort: the odorless velvet fabric absorbs moisture and keeps your feet fresh and dry all day long. The honeycomb design and grip on the bottom prevent the insoles from slipping inside your shoes. The U-shaped heel cup helps maintain stability and position the heel naturally, increasing comfort. • Versatility for sports, work, and leisure: the heel cushion inserts enhance performance and reduce fatigue in daily life. Their cushioning effect reduces impact on joints and muscles, relieving pain caused by leg length discrepancies, heel spurs, and Achilles tendinitis. • Compatibility with different types of footwear: our lift insoles are suitable for most shoes, including boots, athletic shoes, sneakers, high-top shoes, and tennis shoes. They are not suitable for low-cut shoes.
