I just want to report...

On my last trip, 40 miles in 4 days, the Injinji liner socks were the best I've ever experienced! I used a wool/nylon outer hiking sock with them (also used my Bridgedales as the outer sock), and I never once had any hot spots -- that's almost unheard of for me.

REI online only shows a single crew sock, but in-store, I bought some different ones off-the-shelf. I accidentally picked up a low-top "no-show" sock, and worked just as well as the high-tops.

It takes a bit of fussing to put them on, and they always peel off inside out, but no matter. I am sold on them. May never hike again without them.

"Injinji" ought to be "Ninja" -- easier to remember and pronounce.
