Inspection of products is a key quality control process for many manufacturing organizations. Even those with quality management systems such as ISO 9001 often have some form of raw material, in process or final inspection. For some companies without a formal quality management system, inspection and testing may be the only means of confirming product quality and is often a contractual obligation.
Quality is a very important feature of any shoe or footwear you may make, buy, or sell. In this article, you will learn the process of quality control in the footwear industry.
A grade shoes:
Shoes without any functional defects or cosmetic defects that will impair the marketability of the shoe are A grade. These are high-quality shoes, they look good and fit correctly. An A grade must follow the production specifications and match the approved confirmation sample.
B grade shoes:
Shoes without any major functional defects and which will not cause injury to the person wearing the shoes are B grade. B grade shoes may have cosmetic defects, production mistakes, or workmanship issues that cannot be properly repaired.

Shoes are also considered C-grade if they have poor workmanship or materials defects that could shorten the normal life expectancy of the shoe or damage the company’s reputation.

Holding the shoe from the bottom,
roll the uppers together side by side.
You are now checking the alignment of the shoe parts. Starting from the front, roll the shoes to align the parts, toe caps, vamps, overlays, eye stays, and eyelets.

3.2. Any metal part is rusted? Any eyelets is cracking or detached?

3.4. Any dirty mark/ glue mark on unit surface?
3.5. Any quality issue related to surface? Scratching/ dent mark/wrinkle mark on unit?
3.6. Look inside the shoe opening. Is the lining clean and without wrinkles? Run your hand around the collar, feel for any lump, bumps or glue. For leather shoes, be on the lookout for any lasting nails or staples. For sports shoes, make sure the footbed is straight, level, and fitting correctly. If the footbed is too small it may slide around, too big and the footbed may wrinkle or curl.
3.7. Inspect the tongue lining for wrinkles and lumps. Run your hand down inside to check the vamp and toe cap from inside. Feel around the toe along footbed for lasting wrinkles. Feel for any rough stitching inside.
Finally, make a quick check of the laces. Too long is not usually a big problem, too short will have to be fixed!
