Customizing the Sock Toes

[auburnchick]

So, I've done quite a few pairs of socks, and I'm working on a new pair (Hawaiian Leis Socks) right now.

My question...

Why do patterns make you decrease both sides for the toes? Here's a picture of my socks and (gag) a close up of my foot:





So, you see how the big toe goes straight up. Why in the world do I want to decrease on that side?

I've tinkered with the idea of customizing my socks further for a better fit.

What do you think?
