I consider this post valuable for those who have a leg up to 25 cm (up to size 39), since you can buy shoes for yourself not only in the adult section, but also in the children’s section. Why? Children’s models look similar to adults, and their price is usually pleasantly lower.
Alas, this option does not suit me, I have a little more foot, but many friends have long been buying clothes and shoes from the children’s section, all the more often the design is similar to adults, and the price is much lower. If you know your US size, then the calculation formula looks like this: your size minus 1.5 = children’s shoe size. That is, if you wear a size 7, then a child size 5.5 is suitable for you.
