I have the exact same experience. I am about to order another pair and was considering adjusting the measurments. But if they "forgot" to hot soak them the first time and does it on my next order everything will be off.
I dont know much about denim so I asked another guy here, and was told that they probably always will shrink unless you cold wash them.
Mine was washed on 40C, no tumble dry. The shrinkage was more or less exactly what Luxire has mentioned here before.
