Skibo's big feet

Boo (3) has just managed to grow his feet. To the same size as his big sister Boo's: currently a (US size, toddler range) 11.5. It is a weird feature (surely it can't be a bug) of the irrationality of shoe sizes over here that they start out at 1, proceed up to 13, and then return to 1 again, at the age of around 6. For some reason, there is then a distinction made between women's sizes and men's sizes. I'm not sure that the UK system as I recall it is any more rational (though perhaps the sizes of shoes more consistently matched the claimed sizes on the box). I have a sneaking suspicion that the continental system (as in Europe) is more rational, and therefore has absolutely no hope of ever catching on over here.
