I went to look for some new athletic socks last night. I went to the running store where I won a gift card. They did not have a large supply of socks, but the ones that caught my eye were bamboo and wool! They are made for "breathing", wicking away moisture and eliminating odor causing bacteria. That all sounds pretty good for sweaty feet! They also sport a Lycra band across the arch for extra support. And, there is no toe seam. They come in black/charcoal and tan/natural colors.
