Flexible foam
Polyurethane foams are considered the most effective and efficient materials for producing insoles in the footwear industry because they can effectively alleviate pain from prolonged standing. These insoles prevent pressure buildup in specific areas and can even correct and adjust improper body posture. Furthermore, polyurethane insoles maintain their durability over time and exhibit better resistance to compression set compared to other foams with similar density. Shock absorption and dimensional stability are also among the most important features of polyurethane insoles.
