The global footwear industry is changing, but one thing remains clear: making shoes at scale requires more than factory space and labor.

According to the *World Footwear Yearbook 2026*, global footwear production reached 24.6 billion pairs in 2025. Asia accounted for 88.7% of that total.

These figures show how strongly footwear manufacturing remains concentrated in Asia.

At the same time, footwear brands and manufacturers continue to review their supply chains, production locations, and sourcing strategies.

This raises an important question: When footwear production expands or moves to a new location, how can manufacturers maintain the same quality?

The answer involves materials, people, production processes, and the systems used to control them.

1. How Global Footwear Production Is Changing

Asia Remains the Center of Footwear Manufacturing

The latest industry figures show that Asia continues to lead global footwear production.

According to the *World Footwear Yearbook 2026*, the three largest footwear-producing countries in 2025 were:

Country	Global Production Share
চীন	55.6%
India	12.2%
ভিয়েতনাম	6.7%

China remains the largest producer, making around 13.7 billion pairs. India follows with approximately 3 billion pairs, while Vietnam produces around 1.7 billion pairs.

Together, these countries account for a large share of the world’s footwear output.

However, the data also tells us something important: global footwear production is not moving away from Asia as a whole.

Instead, manufacturers are operating within a highly concentrated regional production system, while individual companies may adjust where and how they produce shoes.

Why Production Locations Matter

A footwear factory does not work alone.

It depends on material suppliers, equipment providers, trained workers, transport networks, and technical support.

When a manufacturer opens a new production line or works with a different supplier, these connections may change.

For example, a factory may receive shoe soles from a new supplier or use different equipment to complete the same production step.

These changes do not automatically lead to lower quality.

But they can create new conditions that manufacturers need to evaluate.

Moving production capacity is one task. Maintaining a stable manufacturing process is another.

 2. Why Manufacturing Quality Becomes More Complex

The Challenge of Keeping Materials Consistent

A modern shoe may combine textiles, synthetic leather, EVA foam, rubber, and other materials.

Even when materials look similar, their properties can differ.

Two EVA soles, for example, may have different formulations or surface conditions. These differences can affect how they respond to surface preparation and bonding.

This matters when a factory changes material suppliers or introduces new components.

A material that meets basic appearance and size requirements may still need further checks before it enters the bonding process.

For manufacturers, material approval should consider the requirements of the final application.

Production Conditions Can Change

Quality also depends on how materials are processed.

Temperature, humidity, equipment settings, drying time, and operator practices may affect different stages of footwear production.

Consider a bonding process developed on one production line.

If the same process is transferred to another line, the equipment and operating conditions may not be identical.

The original settings may still work. However, this should be confirmed through process checks rather than assumed.

This is why production consistency depends on both material control and process control.

 3. What Production Changes Mean for Footwear Adhesives

Bonding Performance Depends on More Than Adhesive Selection

Adhesives play an important role in many footwear constructions, especially where different materials must remain connected during use.

But bonding performance is not determined by the adhesive alone.

It also depends on the materials being joined and the conditions used during application.

Several factors may need attention:

• Material properties: Different surfaces can respond differently to the same adhesive.
• Surface preparation: Cleaning, roughening, or suitable treatment may be required for certain materials.
• Adhesive application: The amount and coverage should match the process requirements.
• Drying and assembly: The correct conditions and timing depend on the adhesive system.
• Bonding conditions: Pressure, temperature, and curing requirements must be considered where applicable.

When a factory changes materials, equipment, or production conditions, these factors may need to be reviewed.

Using the same adhesive does not always mean the complete bonding process remains unchanged.

Why Bonding Tests Matter

Testing helps manufacturers understand whether a bonding process meets its intended requirements.

For example, SATRA TM411 is a test method used to measure the peel strength of footwear sole bonds.

It evaluates the bond between the sole and upper, or between bonded layers of the bottom construction, at specified locations on completed footwear.

The results can provide useful information about bond strength under defined test conditions.

However, a single result cannot describe every aspect of a shoe’s performance.

Depending on the application, manufacturers may also need to evaluate heat resistance, ageing performance, or other relevant properties.

The test method should match the performance requirement.

The purpose of testing is not simply to obtain a high number. It is to understand whether the bonding system is suitable for its intended use.

4. What Manufacturers Should Check When Production Changes

A change in production location does not always require a new adhesive.

However, it may require the existing bonding process to be reviewed.

Before Starting a New Production Line

Manufacturers can begin with several practical checks.

1. Confirm material specifications.

Check whether the new materials match the approved specifications. Pay attention to material type, surface condition, and any required treatment.

2. Review process conditions.

Compare the equipment, application methods, drying conditions, and assembly procedures with the approved process.

3. Test the actual material combination.

Use representative materials and suitable test methods to evaluate bonding performance.

4. Check production consistency.

Review how operators, equipment settings, and inspection procedures will be controlled during regular production.

5. Keep clear records.

Document the materials, process settings, test conditions, and results. This helps teams investigate differences if problems appear later.

These checks can help manufacturers identify potential risks before production reaches full scale.

What Should Procurement Teams Ask Suppliers?

For procurement teams, supplier evaluation should go beyond price and delivery.

Useful questions include:

– Can the supplier provide technical information for the intended application?
– What material and process conditions should be considered?
– What testing information is available?
– Is technical support available when materials or production conditions change?

These questions help connect purchasing decisions with the needs of production and quality teams.

 5. The Role of Adhesive Suppliers in Manufacturing Quality

As footwear manufacturing becomes more connected across different locations, technical communication between manufacturers and material suppliers remains important.

Adhesive suppliers can support this process by helping customers understand material compatibility, application requirements, and relevant performance tests.

At HELEY CHEMICAL, we believe adhesive selection should begin with the footwear application.

The materials being bonded, production process, and expected performance all need to be considered before selecting a suitable bonding solution.

This approach is especially relevant when manufacturers introduce new materials or review an existing production process.

Rather than looking at adhesive performance as a separate issue, it is more useful to evaluate how the adhesive works within the complete manufacturing system.

 6. Conclusion: Manufacturing Quality Must Move With Production

Global footwear manufacturing remains highly concentrated in Asia, but individual factories and supply chains continue to evolve.

New production locations, material suppliers, and equipment can create opportunities for manufacturers.

They can also introduce differences that need to be understood and controlled.

For footwear manufacturers, maintaining quality means paying attention to the full production process, from material approval to final testing.

For procurement teams, it means considering technical suitability alongside price and supply reliability.

For engineers, it means checking whether an established process remains suitable when production conditions change.

As footwear production evolves, quality depends on how well materials, processes, and technical knowledge work together.

That is where reliable manufacturing begins.
