Why are there no signs on Qi Le's shoes?

Why are there no signs on Qi Le's shoes? The reasons are: style design, production batch and so on.

1. Style design: The style design of some interesting shoes may not contain logo, or the logo design is small or hidden, which is not easy to be noticed.

2. Production batch: The logo position of Qi Le shoes in different production batches may be different. Some batches may put the logo on the tongue or insole, and some batches may put the logo on the heel or sole.
