I like the way Injinji socks feel, but I don't find them to be nearly as friction-free as my Tekos or even SmartWool - even the wool Injinjis. Plus, they pill easily, and that creates friction of its own.

In any style, I've had to go to a larger sock size, as well as larger shoes. Socks that are too small do compress your toes and force them together.

We're really conflating two things - footwear that lets your toes and foot bones move independently, and footwear that's large enough to let your toes and feet take their natural shape. I'm not near ready for VFFs yet - and anyway they are just a hair short for my toes - but bigger shoes and bigger socks have solved most of my toe problems, anyway.

Foot, ankle and hip problems ... I'm working on 'em.
