Frequently asked questions
How much growing room should I leave?
About a thumb's width in front of the longest toe. More than that can let the heel slide.
What do PS and GS mean?
PS means preschool, the little kids range. GS means grade school, the big kids range.
Is a youth 7Y the same as a men's 7?
They are usually close in length, but check the chart, because width and fit can differ.
