Definitely held up to hiking with hiking boots. No blisters. Keeps your feet warm around the house too. Thick. Feels cushioned. Expensive yes but you pay for what you get. I plan to wear these and order more for a four day hiking trip in Peru at Machu Picchu. Thicker than the kids size although kids size is cheaper and fits me its not as thick and gave me a blister when I hiked compared to these thicker womens size. I normally wear a size six in womens shoes and a size small sock fits just fine.
