I read about these in a book once and thought I'd try a pair; now I have 6. I do a lot of running and it doesn't matter what shoe you have, you can practically run in these alone, these socks feel very comfortable and make running easier. Also, I run obstacle course races, and climbing up and down mountains is much easier with these socks on. For me, I would always get blisters, since using these, I haven't gotten one. I hope this review helps.
