They are a different cut from Wranglers
Wrangler has Slim , Boot Cut , Full ( for skosh more room ) or something along that name ology.
Classic Old West Styles will be high waist
I find if I wear them as high as they intended ( they fit " sorta like cheap Hotel " no Ballroom !
Try a size one up and use the rear belt strap to snug them up....
One caveat though ..... hang them in your closet for a long sabbatical and they shrink
