What is the best shoe size for babies, toddlers or teens?
The best shoe size of babies, toddlers and teens is a question that many parents have. The answer to this question depends on the age and foot size of the child. Fortunately, many children grow up with the same proportions. Therefore, the shoe size can also be estimated on the basis of age for babies, toddlers and even teens. Make sure that there is about 2 cm (0.79 inch) extra room to grow. If the foot is the same size as the shoe, it is too small.

How does the age shoe size trick work?
Did you know that a few years ago there was a trick to estimate your age with your shoe size? The formula goes like this: (Your US shoe size x 5 + 50) x 20 + 1022 – year you are born = shoe size and age
For example, I have shoe size 11 and I am born in 1991. Than it goes like this: (11 × 5 + 50) x 20 + 1022 – 1991 = 1131
Notice the first two digits are the shoe size and the last two is your age. It’s now the year 2022. So that’s why you’re using 1022. In the year 2025, you’re using the number 1025. You can read more about it on another website.
