Frequently Asked Questions
How do the invisible height increase insoles work?
These insoles are designed as wearable "socks" made of soft silicone. You wear them directly on your heels inside your socks, making the height increase completely invisible even if you take off your shoes.
Is the silicone material safe for sensitive skin?
Yes, our insoles are made from medical-grade, high-quality soft silicone (gel) which is skin-friendly, non-toxic, and designed for long-term daily wear.
Will these insoles slide or move while I am walking?
The silicone material has natural anti-slip properties that adhere comfortably to your skin. When worn under socks, they stay securely in place regardless of your activity level.
Can I wash and reuse these height increase socks?
Absolutely. They are fully washable. We recommend hand washing with mild soap and air drying to maintain their shape and hygiene for long-term use.
Are they suitable for all types of footwear?
They are most suitable for casual shoes, sneakers, boots, and high-top shoes. Because they are worn inside socks, they work with almost any closed-heel footwear.
Do you offer OEM or custom packaging?
Yes, OEM services are available. We can provide customized packaging solutions based on your specific brand requirements for bulk orders.
