Hard to find thin socks that are also white. My daughter's feet often get hot in tight shoes, so thin socks are a must. I know there have been some negative reviews about the lack of cotton. These socks are very soft and just what I wanted. I'm glad I ignored the negative reviews. If I hadn't bought the same brand sooner I probably would have been influenced by negativity and would have missed a lot. These socks are 1/3 the price of the ones I bought in the store.
