Chinese Army Pilot Boots 25cm Rare?

I purchased a pair of People's Liberation Army Air Force pilot boots (size 25cm) from a military surplus store in Beijing. They are made of leather with cloth lining and rubber soles. I wore them twice on tours after purchasing them, and then stored them at home for a long period. There are some signs of use on the soles and insoles.

I tried to search for the same boots to determine their value but could not find them. It's possible that they are not imported to Japan.

The store where I bought them seemed to be a government-run military equipment store, as there was a sign stating "Soldiers do not have to wait in line," and when I asked the guide about the reason, they said, "Soldiers never know when they will be called for duty."

Thank you for reading until the end.
