i did a soak on my f380s yesterday and i'm fairly convinced they didn't shrink all the way. my tap water gets hot, but it's not REALLY hot. i'm wondering if i need hotter water. they're 33s and there's plenty of room in them (31-32 true waist). i had KMW 2010s a few years ago and the 33s barely fit after they were washed (i didn't know what i was doing and hot washed them and got them hemmed right when i got them). i've got nudie AJ 32 that are still snug after a soak and a wash, so i'm pretty convinced there's some shrink left in the flatheads.
