Jeans that don't sag in the crotch

It seems like all the jeans I buy or try the rise is way too low. I'm generally a 46w but I have to buy 28L jeans. And the crotch always hangs down halfway to my knee caps. I wear my pants at the waste....or at least where they're comfortable and I don't look like my grandpa. Any suggestions on brands/model jeans that I can try?
I'm 5'10", 240lbs with a flatter butt and thicker thighs.

thanks
