If you go to a different place for leisure or outdoor events, you may not be able to read sudden changes in the weather. However, I found a "shoe cover" with Daiso that seems to be useful when it is not bulky to bring boots.
"Shoe cover" 100 yen (excluding tax)
This product is a rain cover that protects your shoes from rain and mud. It is compatible with shoes of 32 cm or less and can be worn while wearing shoes.
Design that detectives are likely to wear in on-site verification
The height is 24 cm, so high-top sneakers are perfect. Aside from the rubberized cuffs, there is also a drawcord that secures the ankles, so even the author, who has a shoe size of 25 cm, did not have the impression that it was too large. The bottom is designed to be non-slip, but it seems to be slippery on slippery tiles, so you should be careful.
Drawcord firmly guards your ankles (not completely waterproof)
The sole is designed to be non-slip
Also, I felt that the adhesive surface would come off if I moved violently or used it many times, so it seems good to think of it as a simple cover in an emergency. It can be folded compactly, so be sure to use it in your luggage.
Is the adhesive surface likely to come off?
