The Iron Heart IH-126-KHA Type III is made of a 1940s style 12oz whipcord

and a flattering silhouette while keeping a wide enough leg opening for a cowboy or engineer boot

while the crepe sole is subtle enough for wearing around the house yet durable enough to run errands around town

as they are specially double stitched - first with a poly-cotton thread for strength
