Only worn them on one hike so far. I was worried they would be too hot or too thick for my hiking boots, which are a tad narrow. We hiked up a mountain in the summer (up to about 85-90 degrees outside). My feet felt great the whole time. Not hot, not sweaty, not too tight. Really pleased with them. Excited to try them in winter.
