On the one hand, there is a size chart for Adidas-brand children, youth and teen shoes. On the other hand, there is a chart just for women’s and men’s Adidas shoe sizes.

Averages in the U.S. In the United States, the average height for men who are at least 20 years old is around 5 feet 9 inches, with an average shoe size of around 10.5 and a medium width (D).

We already know that as many as 80% of men are actually wearing the wrong size shoe, it's the biggest problem men have buying shoes, and that there are many ways to tell if your shoes don't fit.
