"I have fallen arches, narrow feet, bunions, and I'm a pretty severe overpronator, all of which makes finding comfortable shoes very, very difficult. I've had extremely bad luck with running shoes in the past. I did a little research on these before buying them and they live up to their promise, for sure. The upper part of the shoe was a bit snug at first but it is loosening up as I break them in. The footbed is amazing with great arch support and the sole is both firm and cushy making for a very comfortable run. Also, the material that the soles are made of is really grippy which is nice."
