Ive never had issues with sweating while wearing gortex. Its always breathed well and kept my feet dry. Other boots and shoes my socks were soaked after a trek
It seems my Thinsulate Goretex boots soak with sweat, but these non-insulated Danner Tachyon GTX duty boots do not. I'm thinking maybe they are too well insulated and too warm for the conditions I use them in. 200 grams?
