I picked up a pair and tried them for the first time today while doing some trail maintenance. It was cold outside, at least to me. They made my feet feel a bit pinched but they did keep my feet noticably warmer, but that's not what I was buying them for. They were coolmax wigwam's and I wore them under a pair of smartwool PHD's. The PHD's take forever to dry. What are the real benefits for wearing them and is it neccessarily for everyone or is it a preference thing? Are there other types or better kinds to get? Pro's and cons? Just wondering what the WB's thought.......
