Received my X8 today. Disappointed as hell. There is nothing wrong with the shoe/sock, it looks great. But the sizing is shit. I normally have size 43 or us.9,5-10 so that's what I ordered. The ones I received is marked with 43, us 10 but they cannot be bigger than 41. Both my heel and big toe hangs over the edge of the sole. So if you buy, go up one or two sizes. If I lived in the US I would try to change size, but I live in Sweden, don't know what to do.
