What does cm in shoe size mean?

"CM" in shoe size refers to "centimeters," which is a metric measurement used to indicate the length of the shoe's insole or footbed. This measurement helps consumers find a shoe that fits properly by providing a more precise size compared to traditional sizing systems. For example, a shoe size labeled as 25 cm typically corresponds to a foot length of 25 centimeters. This system is commonly used in countries that utilize the metric system.
