Beautiful and warm socks, knit to last forever. I wear a size 11 1/2 shoe, size 46 clogs, and ordered size 11 socks (size 43/44). The socks arrived today, and fit a tiny bit loosely. The socks have room to shrink, I suppose, but it seems like they are too large. I have other handmade wool socks that are smaller, but because they are knit, the fabric loosens over time to conform. I have a feeling these socks are going to loosen and then will be too big. My advice to avoid return fees is to order a size down (I should have ordered size 10).
