This boot is as advertised.  Lightweight, great ventilation, and comfortable.  I have extra wide feet, and it can be hard to find quality boots that aren't gore-tex.  I was tired of my feet always sweating in the hot weather.  These boots fit the bill, even though they are not wide enough.  The material is forgiving enough to make it work for my feet size.  Overall, a great boot.  It is a training boot, and as such, be careful if you do venture off the beaten path as I have noticed thorns sticking to the soles.
