Just a note, if you buy fleece or some other type of wader pants with a stirrup under the foot, check for seams. Some of those have some big seams that really bite into your ankle and foot when worn with waders and wading boots. I switched from stirrup fleece to a material similar to what Preston described for a fairly seemless fit.
