I typically wear 30 in Walt and a 31 in Rivet. I just tried on the Driggs for the first time today. I actually find the 30 Walt to be just a little bit loose on me now, and the 30 Driggs with a lower rise fit me better.Maybe if the 28 Walt is a tight fit for you, you can go with a 29 Driggs. Honestly, though, like MrClemson says, you will hear all sorts of different advice. You can always tailor the seats. See what works for you in the thighs.
