Socks are much larger than indicated

I have shoe size 43 and has been my experience that socks like to turn out something bigger. Since I do not like that, I ordered a precautionary socks size 39-42. Unfortunately, this size was still totally inappropriate. The heel socks hung elsewhere, and also the length of the sock, I found a little too long for my taste (I'm wearing these socks on business suits). My son has shoe size 45 and him have the socks "like a glove" fit. Because he is pleased with the product gets nevertheless still 2 stars.
