New socks SUCK.
So, we have reached the end of a socks' life expectancy and the inevitable has to happen. New socks arrive. However, due to the ever present problem of childhood growth spurts, the old size for socks is no longer the current size of Crash's feet. Not to mention the old brand is no longer carried at the store. You see Crash is very specific on the type of sock he will wear. It has to be "short" (below ankle cut), it has to have a minimal to non-existent seam for the toe, and it has to be tight fighting (so his foot feels like it is getting a hug when he puts it on). Try explaining that to the clerk at the store.
I would love it if someone could do a study to find out just how many socks of this type actually exist, because I sure can show you all the ones that don't.
