Fiber insole boards are a key material that determines the durability and comfort of footwear.
As demand grows for lightweight and eco-friendly reinforcement materials, fiber insole boards are expanding their applications beyond the footwear industry into bags, furniture, automotive interiors, and construction materials.
What is a Fiber Insole Board?
A Fiber Insole Board is an essential component used inside shoes as an insole base.
Traditionally made from leather or thick cardboard, modern insole boards are now largely made from fiber-based materials that offer greater durability and reduced weight.
These boards are generally categorized into two types:
Paper Insole Board (Pulp Board) : Made by compressing and bonding materials such as wood pulp, recycled paper, and latex resin. This type is recyclable and relatively cost-effective.
Nonwoven Insole Board (Chemical Fiber Board) : Manufactured by needle-punching synthetic fibers like polyester into a nonwoven fabric, then impregnating it with resin-based adhesives and curing the material. It is ideal for shoes that require high strength and elasticity.
Applications of Fiber Insole Boards
Fiber insole boards are widely used in various types of shoes and are also applied across industries as lightweight reinforcement boards.
Footwear Industry : Used in almost all types of footwear—sneakers, dress shoes, casual shoes, boots, hiking shoes, safety shoes, and work shoes. They help distribute foot pressure and maintain the shoe’s structural integrity.
Bags and Accessories : Utilized as bottom boards in bags, internal frames in travel luggage, and reinforcements in wallets or belts. Compared to leather, fiber boards are lighter and offer excellent shape retention, making them ideal as internal reinforcements in luggage and premium bags.
Furniture Industry : Applied to structural components such as sofa base boards, chair backrests, and bed frame panels. Their shock-absorbing and form-stabilizing properties make them suitable as internal materials in furniture, offering advantages in weight and workability over plastic or metal.
Automotive Interiors : Used in door trim panels, trunk reinforcements, and under-dashboard boards. Water-repellent compressed fiber boards (Cowlboards) are suitable for parts requiring moisture resistance and strength. Polyester nonwoven board technology is often applied here.
Construction Materials : Produced in a form similar to MDF, fiber boards are used in acoustic panels and interior boards. In eco-friendly building designs, natural fiber boards are increasingly replacing plastic or foam boards.
Fiber insole boards are gaining traction as reinforcement panels that combine lightweight properties, durability, and sustainability.
Their applications continue to grow across industries beyond footwear.
