Fantastic year round. I've worn green for years and decided to try the wool, I'll never change back. Doesn't matter if it is summer or winter the wool regulates and my feet are warmer in the winter and cooler in the summer. The other review mentions the wool pulling down from the edges of the heel, they do. But I don't think I've noticed it being a problem since I've been in this pair for a year now.Show More Show Less
I've been a using Superfeet green insoles for years, so I was excited to see them done with merino wool. They fit just like the green insoles but have a nice, warm wooly feel. I was about to buy a second set when I noticed that the wool tends to peel down away from the edges of the heel cup after a few weeks of use. Too bad, because they're great otherwise.Show More Show Less
