I ordered these to replace a boot that was taller but would not fit around my calves. These fit but are not as comfortable as i would like. No arch support and the fur  keeps falling off. I usually wear a 10 so ordered and 11 and still seemed to run small. Also because they are shorter the mud that is kicked up when you walk hits you on the back of the leg and dirt and gravel fall into the back of the boot if you wear them with out pants. So they work, just not all that great.
