So, when I started this blog, I was amazed to see a size 7Y, because this has always been a men's size when I was growing up.
How have things changed!
There is almost universal agreement that 7 is clearly a boys size.
But there are now even larger youth sizes
There are 8Y
9.5Y
And even 10.5Y!
Clearly, even double digits aren't safe from being considered boys size.
