The laces that came with my Red Wing Iron Rangers were awesome. They held up for about a year, but then needed replacing. I bought 5 different colors from FootGalaxy, all in the 54" variety. They're all awesome, and they've held up great for the past few months. I ended up getting a replacement set of original laces from Red Wing, but still haven't put them on, because I love these laces so much.

They thread easily, stay tied, and aren't waxy/stiff. They do get dirty fairly easily, but a quick run through the washing machine and they're all better.
