The socks are interesting but not overwhelming to knit. The structure of the sock is basic top down, but you could turn the pattern around and start from the toe.

The cuff pattern is stretchy and it has shaping built into it. It can be adjusted by by starting off with fewer stitches or by adding a few.
The length of the leg and foot are easily adjustable.
