I mean just the different shoes size conversion, NOT between street shoes vs ski boots.I think the point is that there isn't one, or at least not an accurate one. For instance, mustski, scrapula and I all take a size 9 street shoe, but I'm in a 24.5, mustski's in a 25, and scrapula's in a 25.5!
After all, ski boots uses "international size", meaning the number is the centimeter. But there's no conversion between what's "US size", vs "European size" vs "international size".
I only know of the conversion between the 3 for my size: (US) 6.5 = (Europen) 37 = (International) 23.5
My boot size is 22, which is 1 1/2 centimeter shorter than my street size.
But what about the rest of the sizes?
