The formulas to calculate your shoe size based on your foot length are:
\[ \text{USM} = (3 \times L) - 22 \]
\[ \text{USF} = (3 \times L) - 21 \]
\[ \text{USC} = (3 \times L) - 9.67 \]
Where:
A shoe size is a standard way of displaying the length of a shoe so that people can more easily understand the proper size for their feet.
Let's assume the following value:
Using the formulas to calculate the shoe sizes:
\[ \text{USM} = (3 \times 10) - 22 = 8 \]
\[ \text{USF} = (3 \times 10) - 21 = 9 \]
\[ \text{USC} = (3 \times 10) - 9.67 = 20.33 \]
The Men's Shoe Size is 8, Women's Shoe Size is 9, and Children's Shoe Size is 20.33.
