Youth to adult soccer cleat size conversion
US youth soccer cleat sizes run from 1Y (roughly EU 32) to 6Y (roughly EU 37); US adult cleats start at size 7 (EU 39), so a child moves out of youth cleats once their foot exceeds a US 6Y, typically around age 13-14 for boys and 12-13 for girls.

Frequently asked questions
How do youth soccer cleat sizes convert to adult?+
US youth sizes 1Y-6Y run smaller than adult sizes. A US 6Y is roughly a US men's 6, and a US 5Y equals a US women's 6.5-7. Above US men's 7 there is no youth equivalent - it's all adult sizing.
When should a kid switch to adult soccer cleats?+
When their foot is size US 7Y or larger, or roughly age 13-14 for boys and 12-13 for girls. Adult cleats have stiffer soles and firmer studs suited to bigger, stronger players.
Are men's and women's soccer cleats different?+
Most soccer cleats are unisex. Women-specific lasts (last = shoe shape) are narrower in the heel; try both if you can. Sizing runs about 1.5 sizes different between US men's and US women's.
Why do youth cleats fit differently than adult?+
Youth cleats use softer materials, more forgiving lasts, and shorter studs for lighter body weight. Adult cleats prioritize power transfer with stiffer plates.
