I bought a pair of Injinji toe socks recently to try them out. To date, I haven't noticed a huge difference in the way I perform my physical activities (mostly kung fu and an occasional run). If there is a difference, I'm not physically perceiving it at all. I have noticed that the material does make a difference in reducing moisture, but the sock's primary design and function eludes me.
What is the purpose of the toe sock's design, and what effect does separating the toes in a sock have on the bio-mechanical performance of the foot when doing various sports-related activities?
