1. How Global Footwear Production Is Changing<\/h2>\n
Asia Remains the Center of Footwear Manufacturing<\/strong><\/p>\n The latest industry figures show that Asia continues to lead global footwear production.<\/p>\n According to the *World Footwear Yearbook 2026*, the three largest footwear-producing countries in 2025 were:<\/p>\n 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.<\/p>\n Together, these countries account for a large share of the world’s footwear output.<\/p>\n However, the data also tells us something important: global footwear production is not moving away from Asia as a whole.<\/p>\n Instead, manufacturers are operating within a highly concentrated regional production system, while individual companies may adjust where and how they produce shoes.<\/p>\n A footwear factory does not work alone.<\/p>\n It depends on material suppliers, equipment providers, trained workers, transport networks, and technical support.<\/p>\n When a manufacturer opens a new production line or works with a different supplier, these connections may change.<\/p>\n For example, a factory may receive shoe soles from a new supplier or use different equipment to complete the same production step.<\/p>\n These changes do not automatically lead to lower quality.<\/p>\n But they can create new conditions that manufacturers need to evaluate.<\/p>\n Moving production capacity is one task. Maintaining a stable manufacturing process is another.<\/strong><\/p>\n The Challenge of Keeping Materials Consistent<\/strong><\/p>\n A modern shoe may combine textiles, synthetic leather, EVA foam, rubber, and other materials.<\/p>\n Even when materials look similar, their properties can differ.<\/p>\n Two EVA soles, for example, may have different formulations or surface conditions. These differences can affect how they respond to surface preparation and bonding.<\/p>\n This matters when a factory changes material suppliers or introduces new components.<\/p>\n A material that meets basic appearance and size requirements may still need further checks before it enters the bonding process.<\/p>\n For manufacturers, material approval should consider the requirements of the final application.<\/p>\n Production Conditions Can Change<\/strong><\/p>\n Quality also depends on how materials are processed.<\/p>\n Temperature, humidity, equipment settings, drying time, and operator practices may affect different stages of footwear production.<\/p>\n Consider a bonding process developed on one production line.<\/p>\n If the same process is transferred to another line, the equipment and operating conditions may not be identical.<\/p>\n The original settings may still work. However, this should be confirmed through process checks rather than assumed.<\/p>\n This is why production consistency depends on both material control and process control.<\/p>\n Bonding Performance Depends on More Than Adhesive Selection<\/strong><\/p>\n Adhesives play an important role in many footwear constructions, especially where different materials must remain connected during use.<\/p>\n But bonding performance is not determined by the adhesive alone.<\/p>\n It also depends on the materials being joined and the conditions used during application.<\/p>\n Several factors may need attention:<\/p>\n When a factory changes materials, equipment, or production conditions, these factors may need to be reviewed.<\/p>\n Using the same adhesive does not always mean the complete bonding process remains unchanged.<\/p>\n Testing helps manufacturers understand whether a bonding process meets its intended requirements.<\/p>\n For example, SATRA TM411 is a test method used to measure the peel strength of footwear sole bonds.<\/p>\n It evaluates the bond between the sole and upper, or between bonded layers of the bottom construction, at specified locations on completed footwear.<\/p>\n The results can provide useful information about bond strength under defined test conditions.<\/p>\n However, a single result cannot describe every aspect of a shoe’s performance.<\/p>\n Depending on the application, manufacturers may also need to evaluate heat resistance, ageing performance, or other relevant properties.<\/p>\n The test method should match the performance requirement.<\/p>\n 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.<\/strong><\/p>\n A change in production location does not always require a new adhesive.<\/p>\n However, it may require the existing bonding process to be reviewed.<\/p>\n Manufacturers can begin with several practical checks.<\/p>\n Check whether the new materials match the approved specifications. Pay attention to material type, surface condition, and any required treatment.<\/p>\n Compare the equipment, application methods, drying conditions, and assembly procedures with the approved process.<\/p>\n Use representative materials and suitable test methods to evaluate bonding performance.<\/p>\n Review how operators, equipment settings, and inspection procedures will be controlled during regular production.<\/p>\n Document the materials, process settings, test conditions, and results. This helps teams investigate differences if problems appear later.<\/p>\n These checks can help manufacturers identify potential risks before production reaches full scale.<\/p>\n For procurement teams, supplier evaluation should go beyond price and delivery.<\/p>\n Useful questions include:<\/p>\n – Can the supplier provide technical information for the intended application? These questions help connect purchasing decisions with the needs of production and quality teams.<\/p>\n As footwear manufacturing becomes more connected across different locations, technical communication between manufacturers and material suppliers remains important.<\/p>\n Adhesive suppliers can support this process by helping customers understand material compatibility, application requirements, and relevant performance tests.<\/p>\n At HELEY CHEMICAL, we believe adhesive selection should begin with the footwear application.<\/p>\n The materials being bonded, production process, and expected performance all need to be considered before selecting a suitable bonding solution.<\/p>\n This approach is especially relevant when manufacturers introduce new materials or review an existing production process.<\/p>\n 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.<\/p>\n Global footwear manufacturing remains highly concentrated in Asia, but individual factories and supply chains continue to evolve.<\/p>\n New production locations, material suppliers, and equipment can create opportunities for manufacturers.<\/p>\n They can also introduce differences that need to be understood and controlled.<\/p>\n For footwear manufacturers, maintaining quality means paying attention to the full production process, from material approval to final testing.<\/p>\n For procurement teams, it means considering technical suitability alongside price and supply reliability.<\/p>\n For engineers, it means checking whether an established process remains suitable when production conditions change.<\/p>\n As footwear production evolves, quality depends on how well materials, processes, and technical knowledge work together.<\/strong><\/p>\n That is where reliable manufacturing begins.<\/p>\n —<\/p>\n \u00a0References<\/strong><\/p>\n 1.
