How do I know if the shoe fits me

1) because the right side of the body and the left side of the body is different I always try both shoes

2) It is necessary to try them with the right sock for me to get a better picture and result. Although there are Standards for the correct use of a sock in the corresponding shoe, the type of sock can be a personal preference. In this case I always make sure to try on the shoe I bought as I intend to wear it (e.g. a shoe worn with a bare foot is more fitted than a shoe worn with tights. So when we try on the panty hose, if we intend to wear it with tights, it should be tried on with tights and not barefoot).

3) If the tread from the beginning fits the curve of the shoe correctly, then my shoe fits
Shoes only open in width, never in length.
When there is a Kochi or a callus it is important that they do not touch the cat, as the cat does not open.
The softer a skin is, the more elasticity it has. Conversely, the harder the harder, the less elasticity.
