On sale purchase and glad I waited.
Size: 33W x 30L, Color: Stone
I'm 6'1 186lbs size 33x30, I don't workout but for whatever reason my calves pose a problem with a few brands and styles of pants. These feel wonderful and the color is awesome. Minus the tight area in the calves these are perfect for summer in Oklahoma. I usually wear these with light brown or gray penny loafers no socks or some suede Allen Edmonds chelsea boots and a white vneck tshirt. I got these on an extremely good sale so that helps. I wouldn't pay full price for whatever that's worth.
