^actually, I do a 3rd soak after a few days wear, as well.
i hate schlepping around with a ton of fabric bunched up in the ankles like leg weights. I try to get most shrinkage out of the way w/o having to wash, so I can have em hemmed up to appropriate length.
Btw, on the 702s, u should've sized up. Dont invest too much faith on "fully/partially sanforized" not shrinking cuz they're still 100% cotton ... maybe not as much as unsanforized, but still ....
IMO, always size to keep ... Not for [initial] fit ... unless ur planning on NOT washing them at all or maybe sell/swap them out with something else once ur done w/ them , like what some peeps do
