I use these for all my training/running. Cheap, I like white, and have lasted for months without fray. Idk how many miles are on them but probably over 200. Very comfortable, never ever foot pain and I have relatively wide feet. *Disclaimer* My avg runs are only a 5k in distance, sometimes I go more but never over a 10k, so not sure how these would perform over extensive distances.
