This is an absolutely fabulous boot; I wear them just about every day.  They are light for a field boot, water repellent enough (unless you are going to be standing in water), breath and very comfortable.  The leather appears to be top quality and the rest is either Kevlar or something like it.  I've never see a boot made this well.  Usually I don't pay much for shoes/boots, but I feel the ~$200 was well spent here.
