The original designer of banana socks is unknown

Here is the pattern I put together that works for average adult feet.

EDIT
I noticed some of you made modifications and I liked them! So I’m including a list here

1) For toe increases, use KFB instead of M1R/M1L (easier)

2) After the increases, start with purl rounds instead of knit rounds. (looks prettier)

3) Change bottom stitches from (k2-p2) to k-(p2-k2)-k (looks prettier)

Thank you for your suggestions, and happy knitting!
