Salomon X Ultra mids for lighter pack training, and trail running with no pack.
I throw my Garmont Antelao boots on when training with heavier pack weight (35lbs+). These are the same boots I will hunt with when in the backcountry.
KEENS!!!!!!! For over five years now that's all I wear. Work play excersise. Every pair I've bought fit right out of the box with no break in period. I've had the low tops for trail running, mid height for running with a pack and high top stiffer ones for heavier packs.
