It is believed that these were used by flight department officers who had modified their existing summer flight boots into boots.
It looks like they have been remade from medium-sized flight shoes by making the torso and toes slimmer, and you can see part of the punching out of the ``medium'' character on the inside of the back.
The leather upholstery on the inside has also been changed to a slightly harder leather, and the lining cloth seems to have been changed from national defense colors to white cotton cloth.
Also, the cloth hanging cord has been removed and eyelet holes have been made inside.
The toe part, which was originally rounded, seems to have been narrowed down to a boot-like shape.
For reference, we are comparing the small issue of winter flight shoes.
This is a used item with some damage on the side of the sole and a slight blackish discoloration on the toe area.
Other conditions are relatively good.
The rubber on the sole of the shoe originally has a suction cup-like pattern embedded with aluminum, but this product has black solid rubber pasted on it.

Although these are modified official items, there are only a few flying shoes designed for officers, so they are considered to be valuable materials.
