I like the color but they WrinKLE UP~!!!!

I bought a pair in Sidewalk color about a couple of months ago and now as I was looking for replacing old pairs with a new pair of jeans i have to say that these jeans Wrinkle up really bad.I have purchased 511's before so i know my fit really well, but compared to other washes these color washes like the neautral , sidewalk, khaki , and other solids have this harder denim material or composition and this stiffness doesn't look so good on the knee and down to the shin. I mean i have other washes like the faded black which is made with a softer denim and i dont get as much wrinkling and bunching up as i do with the Solid colors. I never returned these because i still like the color and am looking to soften up these jeans without tumble drying them since tumbling them will shrink the fit and this I never like doing ( I always line dry these at night). But i dont think there is a cure for how they bunch up at the bottom of the leg, it looks aweful, it looks like well it looks bad. If you go to the levis website and just look up the colors and neutrals section and you will see that they crinkle up more than the blue denim washes and they krinkle up in the best of photo shoots. Beware with these colors they are to me one of the worst 511's , but i like the colors, but i dislike how they bunch up :(
