Oh my goodness that is funny. Did they come in the same package?
This is another one of those posts I tried commenting on but could not. I think the problem (as I have with long-sleeve shirts) is that there really are no international sizing standards. My guess is that the sock on the left was manufactured in a country like Taiwan or India where stereotypically, the populace is smaller in stature. I'm thinking the one on the right came from the US. Maybe I'm wrong. Still, imagine if you can how incredulous someone in Taiwan or India might be that a 12-24 month old would have a foot "that big!" Just a thought.
