The selection of materials for height-increasing insoles needs to be combined with comfort, durability and functional requirements. The following are the characteristics and applicable scenarios of common materials:
1. Silicone material
Features: Lightweight and soft, good breathability, good elasticity, and has a certain antibacterial and deodorizing effect.
Disadvantages: Poor anti-slip and wear resistance, easy to hydrolyze in contact with water, resulting in a shortened service life.
Applicable scenarios: Daily casual insoles, suitable for scenarios with low anti-slip requirements.
2. EVA (ethylene-vinyl acetate copolymer)
Features: Excellent cushioning and shock resistance, light and corrosion-resistant, but poor softness and general comfort.
Applicable scenarios: Footwear that requires good shock resistance (such as sports shoes), but long-term wearing may affect the foot feel due to hardness.
3. Polyurethane (PU)
Features: Low density, soft and comfortable, light and wear-resistant, shock-absorbing and anti-slip, good temperature resistance and strong dimensional stability.
Applicable scenarios: Universal height-enhancing insoles, especially suitable for users who pursue comfort and durability.
4. Air cushion shock-absorbing material Features: Significant shock-absorbing effect, high softness, but inferior products are prone to air leakage or short life.
Applicable scenarios: Sports shoes or scenarios with high shock absorption requirements, you need to choose brand products to ensure quality.
5. Popcorn material Features: Excellent elasticity and softness, outstanding shock absorption effect, but the price is higher (usually 2-3 times that of ordinary insoles).
Applicable scenarios: Users who pursue extreme comfort (such as running or long-term standing occupations), but need to consider cost-effectiveness.
6. Memory foam material Features: Automatically adjust the shape according to the foot shape, providing personalized support and comfort.
Applicable scenarios: Scenarios that require customized support (such as arch problems), but be aware that the breathability may be weak.
Purchasing advice: Choose materials based on usage scenarios (such as air cushion for sports and PU for daily use), and make sure the height does not exceed 5 cm to avoid excessive pressure on the feet.
