Rub your feet with Body Glide, a runner's product available at Dick's Sporting Goods (looks like a deodorant stick).
Spray your feet with antiperspirant.
Wear shoes that don't make your feet sweat. There are dozens of comfy, supportive sport sandals on the market.
But if you really must:
Any lightweight synthetic will work UNDER an absorbent non-cotton sock.
Polypropylene, polyester, and wool liners all work. My favorite is silk - breathable, not stinky, and temperature-regulating.
Outer sock could be wool, wool/poly blends (such as CoolMax), fleece, or polyester.
If you want to get really fancy, get the silk kind with separated toes.
And don't forget your Moleskin!
