Overall I like these shoes but anyone who buys them should know that they are very light and quite narrow. I used to have trail shoes that easily weighed twice as much as these. I'm a bit worried they will be less durable but only time will tell. They are also the slimmest shoes I have ever owned. I have medium wide feet and thought these shoes would put a lot of pressure on them but they are still comfortable. People with wide feet may find these shoes a little tight. After a week of trail running, I can add that these shoes are not made for rougher terrain than dirt or gravel. The sole is too thin for rocky terrain.
