Most boys continue to wear toddler shoes until they are 4 or 5 years old. For instance, some 4-year-old boys will wear a size 11 toddler shoe. We sometimes denote sizes for toddlers with a “T,” so a size “11T” would be a size 11 in toddler shoes.

The “youth” shoe sizes are next. Sizes for these, which range from 1 to 7, are frequently denoted with a “Y,” so a size 1Y would correspond to a size 1 in youth shoes. Size 1Y shoes are larger than size 13T shoes; youth sizes are for bigger boys. It’s time to transition to adult shoe sizes once your child outgrows the largest 7Y shoes.
