I would use a zig zag stitch if possible, one that takes smaller stitches in every zig zag, i.e., a stretch stitch.
Finally someone came up with the hint about the needle. That is very important when sewing on knits, and even more so with this application. I would sew a new line down the whole leg, making it narrower. That way, one line of sewing medium to large stitches would suffice.
And everybody: cut those big toe nails. I don't have that problem anymore. My fungal nails don't grow, so don't cut up my socks. Ha ha!
And good luck.
