Whether you are importing shoes from shoe manufacturing companies in China, Indonesia, India, or Vietnam, what needs to be looked at is cosmetic defects and non-cosmetic defects. And, functional defects shouldn’t be tolerated at all.

Usually, with China wholesale shoe manufacturers, you don’t have to worry about the quality checks. With thousands of shoe factories in Guangzhou, China, leading footwear companies such as Nike put their faith in Chinese industries.

Let’s have a look at various shoe defects each factory owner must identify and fix.

  1. Excess Glue or Wax:

Shoes being sold at discounted rates are commonly found with this cosmetic defect of excess glue or wax oozing out from the sole corners. The reason for low quality workmanship is rushing through the orders.

During the manufacturing process, these glue, oil or wax excess marks can be easily wiped out. But, if it stays past the manufacturing process, it can be very unsightly for the customer to choose it.

It’s imperative to train your workers to use minimal or adequate amount of wax or glue; and to wipe it off if it oozes out then and there. You can save a thousand shoes from returning to your factories.

  1. Weak Cementing:

A common occurrence in case of rubber soles like those in sneakers. Weak cementing occurs when inadequate amount of adhesive glue is applied to the rubber sole. Or if the shoe manufacturer company isn’t using the right type of adhesive or low quality adhesive, their shoes are found with this common defect.

However, this shouldn’t be confused with soles coming off after a year of usage due to undue hot weather conditions.

Being a shoe factory head, you must check if the workers are using high-quality shoe adhesive and if they are using ample amount of glue or not.

  1. Abrasive Marks:

Shiny leather shoe skins are quite delicate and glossy. Abrasive marks can immediately become prominent if not dealt with care. It’s due to poor handling and packaging of shoe during the shoe production process.

To ensure quality check regarding perfect handling of shoes by your workers, ensure that they wear gloves during work. Check if shoes are being moved unnecessarily between workers and being roughly dealt due to bulk order. Most of all, make your packaging smooth enough to prevent any abrasive marks.

  1. Asymmetry:

Asymmetry is another common shoe manufacturing defect that is a very prominent cosmetic defect. There can be asymmetry in certain parts of the shoe. One shoe maybe higher than the other. There can be print difference due to improper cutting or fitting during the manufacturing process.

To identify asymmetry, you can simply place the pair together and check whether there are any differences. Have a few workers committed to checking the width, height, color, cutting, print design, etc. for each pair of shoe. Also, check for the color bleeding across the blocks or on the rubber soles. Even one failure can cost you millions of dollars!

  1. Incorrect Sizes:


It’s not the shoe size that’s awry but the labelling that makes the whole situation worse. Although there isn’t any cosmetic defect, but this can be a great issue when it comes to selling them.

Usually incorrect sizing issues don’t arLeather shoes manufacturerise due to well-sorted shoe production processes. But, if sorted wrongly and packaged wrongly, it can be a huge trouble.

Make sure your employees are handling, packaging, and storing the shoes in an organized manner no matter how huge the orders may be.

  1. Sharp edges and Nails


Sharp edges and protruding nails are a common quality defect that makes shoes unwearable and the shoe manufacturer unreliable. Footwear are all about comfort over style.

Men’s leather shoes mostly require nails for binding the sole. And, if the sharp ends aren’t pressed down, they can protrude into the sole that can be hurtful to the customer when trying on the shoes.

If the sharp points occur due to a factory process, they should be immediately eliminated.Top shoes manufacturer
