I have a sock pattern that is very easy. It's a women's sock pattern actually, but I knit them for my sons and my husband.
Our youngest son is a gym rat, and his legs press over 1,000 lbs. Point is he doesn't have chicken legs!
My husband had polio and one leg/foot is smaller than the other.
I'm sharing those things because the same pattern works for them all. I believe it's the perfect sock pattern.
It looks like you knitted cable socks, but you didn't.
There isn't the ribbing across the top, so it doesn't make marks and pinch leg parts.
It's done on magic loop, so it's so simple, easy peasy!
I know probably some people will roll their eyes, but I'm going to say the pattern is fail-safe. Absolutely every time I make a pair (usually one every two weeks in between other things) it always works up perfectly. No glitches. No problems.
It's a 56 stitch cast on, with a 7 stitch pattern. So you could very easily add 7 more stitches if you felt that your husband needed more. But honestly, the way the socks knit up I believe you'll be surprised that you don't need to make an adjustment.
You just knit the foot of the sock to the person, no adjustments to be made, no changing the pattern. You just knit to 1.75 inches of their toe and then decrease for the toe.
See? Easy Peasy! If you think it might be just what you're looking for let me know! (I just washed 3 pair that were worn throughout the week by my men. Funny that I would check in here and see this.)
Good Luck finding the perfect sock! Our family has the perfect sock!
