The 8 inch measurement would be around his leg, so I think your best bet is to either measure that or a pair of his socks and then see if the 48 or 52 would be better.
ok I just looked and the pattern says to knit 6" to top of heel -
My husband has very muscular legs but I didn’t realize his legs were quite this big. :teehee:
his calf measures 14.5 & 15" at it’s biggest point on each leg and at the top point of the sock his leg measures approx 12.5"
So I am really worried that won’t be near enough give!
It’s a good think you had to check! Maybe you should knit a couple of inches of maybe 64 stitches and see how it would fit on his massive manly calf. :teehee:
You usually want some negative ease in your socks so they stay where they’re supposed to, I think the “usual” is to have the cast on measure 25% less that the actual measurement of the calf where the sock will be.
If you increase your cast on, it will make the whole sock circumference larger, but you can do some calf shaping/decreasing as you work down the leg part (unless he has massive ankles as well, LOL), that way when you get to the heel flap, heel turn, etc. you can follow the directions as written.
