However, after replacing the given footbeds with a thinner alternative, I can also fit into 10.5D, and 10D, 4273s no problem. The 4273 is the second most popular boot for firefighters ever made by Red Wing Shoes. They are NFPA certified fire boots, measure 8 inches from the bottom of the heel to the top of they boot, have melt resistant soles, and are made of Black Yukon Leather, which is waterproof and extremely durable.
In order to maintain their waterproof quality, only waterproof conditioners should be applied to the boots, such as Red Wing's Naturseal conditioner. Despite it's popularity among firefighters, it's uncertain if Red Wing will bring these back into production, so they may not be available much longer. The zippers included with the boots are from the original zipper kits made by Red Wing Shoes.
Which also meets the standards set by the NFPA. Even if it's possible Red Wing may bring back the 4273s into production, what's more uncertain is if the zipper kits will become available again, considering they were discontinued long before the 4273s stopped being made. It's worth mentioning that the size 9.5EE, and 11D, 4273s are factory seconds, but there aren't any considerable flaws as far as I can tell. Factory seconds can be identified by a small hole that's punched into each of the tongues. Red Wing factory seconds may have a flaw, or flaws, that are aesthetic, but they don't have anything to do with the built-in quality and durability of the shoes.This item is in the category "Clothing, Shoes & Accessories\Men\Men's Shoes\Boots".
