In today's insole industry, many suppliers handle only a single part of the process — design, material sourcing, or manufacturing — which often leads to communication gaps, longer lead times, and inconsistent quality.
Datong & Bangni eliminates those barriers through a vertically integrated development and production system that covers every stage of the product lifecycle. From material innovation, R&D, and mold engineering to intelligent manufacturing, quality testing, and global delivery — every process is seamlessly connected and guided by data, expertise, and innovation.
Our in-house engineering and testing capabilities ensure that each insole meets rigorous international standards for performance and comfort.This unified approach not only enhances efficiency and precision but also enables brands to bring customized, high-quality products to market faster.
As your strategic partner, Datong provides end-to-end OEM, ODM, and OBM solutions, helping global brands achieve long-term growth through reliability, innovation, and sustainable development.
The Product Journey
INNOVATE
Our innovation process starts with what we know best: feet, movement, and materials. Backed by decades of insole expertise, orthopedic talent, and data collected from diverse user groups, we uncover insights that define the direction of each new product.
Through continuous material exploration, biomechanical analysis, and early-stage prototyping, we turn these insights into meaningful product concepts. For us, innovation is the engine that drives better comfort, better fit, and better solutions for every category.
DESIGN
Maximizing your insole’s comfort and functionality starts with thoughtful design. At Datong, we collaborate with your team from the early concept stage, leveraging the expertise of our footwear and orthotic engineers to optimize each insole for fit, support, and durability.
Our hands-on, consultative approach ensures every aspect is carefully considered—from material selection and cushioning density to shape, structure, and production methods. We work with you to streamline design, minimize risk, and create insoles that deliver exceptional performance and comfort for every wearer
DEVELOP
The development phase brings your insole from concept to fully realized. At Datong, we collaborate closely with your team ，guides your design through prototyping, mold development, and scalable production.
Our professional teams—including insole engineers, orthotic specialists, and mold technicians—work alongside you to refine cushioning, arch support, contours, and material selection while optimizing manufacturing processes and sourcing. We focus on enhancing comfort, durability, and performance, ensuring your insoles are both effective for the wearer and efficient to produce.
By engaging early, we provide a structured, end-to-end development process that transforms ideas into high-quality, market-ready insoles while minimizing risk and accelerating time to market.
INNOVATiIVE R&D TEAM
We bring together leading minds in Foot Medicine, digital Modeling & Development, and systematic Design Strategy to collaboratively engineer our advanced insole solutions.
TEST
The testing phase validates each insole’s performance, comfort, and durability before mass production. Our in-house laboratories and professional test teams conduct rigorous evaluations — from core materials and surface fabrics to finished insoles — measuring cushioning response, arch support, and long-term comfort across diverse environments and user profiles.
Insights from scientific testing and user feedback are then translated into design improvements, ensuring every insole not only fits perfectly but also performs reliably from the first step to long-term wear.
SOURCE & PLAN
For every project, we align material sourcing and production planning with real-world demand across all categories — from PU and EVA foams to fabric and various components. Once a project is approved, we prepare a detailed BOM and work instructions, specifying materials, components, and technical requirements.
Based on the BOM, we manage procurement by selecting reliable suppliers, ensuring timely delivery of critical materials. At the same time, we develop a production plan that aligns capacity, timelines, and resources to guarantee efficient, on-schedule manufacturing. By combining predictive analytics, real-time production data, and supply chain expertise, we minimize waste, mitigate risks, and ensure high-quality insoles are delivered reliably to our brand partners worldwide.
MANUFACTURE
At our China and Vietnam facilities, advanced production lines—from thermoforming and compression molding to liquid PU casting, foam molding, injection molding, and open-pour polyurethane—ensure every insole meets exacting standards.
From rapid prototypes to full-scale manufacturing, we deliver consistent quality, tight tolerances, and dependable lead times. Our integrated setup supports orthotic, work, outdoor, comfort, and fully custom insoles with repeatable accuracy and industrial-grade reliability.
“What does it mean to be a factory that truly serves brands?
It means mastering professional products, delivering professional service, and always thinking from our customers’perspective. This is the principle we uphold, and the commitment that drives every step we take.”
— CEO, David Qin
DELIVER
Our delivery process ensures every insole order reaches customers accurately, safely, and on schedule. With manufacturing bases in China and Vietnam, we optimize shipping routes, consolidate orders, and coordinate export procedures to support fast, cost-efficient global delivery.
By integrating logistics planning with production schedules, we reduce lead times, maintain supply stability, and provide real-time visibility throughout the shipment. Whether delivering thousands or hundreds of thousands of pairs, we ensure consistent quality, secure packaging, and dependable fulfillment for brand partners worldwide.
SERVICE
Our service doesn’t end at delivery — it continues through every stage of your insole program.We offer ongoing technical support, performance checks, and replenishment planning to keep supply stable and quality consistent.
Whenever questions arise, our sales representatives respond quickly with clear solutions. We also conduct regular market visits worldwide, engaging directly with local partners to gather real insights on product performance and consumer feedback.
These real-world observations feed back into our design and development process, enabling us to refine materials, structures, and future orders
