What socks do you prefer?

Buying my first pair of lightweight shoes and will be doing several week long trips this summer. Should I stick with my thicker Smartwools I've always used in boots or go thinner?

I need to have the right socks before I buy my shoes.

What i have is something like this: https://www.smartwool.com/default.cfm#/Mens/Socks/PerformanceSocks/Outdoor/227/
