^^do NOT soak, unless you want a flat, lifeless, non-crispy pair from the get-go. N&F are unsanforized so shrinkage will be minimal. Also, when its time to wash, a washing machine will do fine...JonSmythe has no idea what he's talking about.
the length will shrink a little as the honeycombs behind the knees settle in (about .5-1 inch). They'll also shrink about an inch (maybe less) after the first wash...but also remember they'll sag a little lower after some wear. You should be ok if you leave enough material to be able to make a 1 inch cuff with just a little break. Enjoy your first raws
if you only plan on wearing them on weekends there's no need to worry about fading. Faint fading will begin appearing after ~3 months of EVERYDAY wear, so you should be fine. Also, don't soak them. That'll remove the sheen the new denim has and make them look 'flatter' and lighter in color.
hows the dye on those nubuck hi's? I got the red ones from fw10 and the color rubs into white laces like crazy. Anyone have another pair of colored nubucks that's had this happen? Only other color I've handled is white and those obviously aren't as saturated.
