Yes, every BRUNT boot has a variety of ASTM ratings. They are also EH rated, slip and oil-resistant, and feature high-heat resistant outsoles up to 572˚F.
There is a removable gray insert below the insole of all of our boots. By removing the gray insert, you can turn your Regular fit (D) boots into a Relaxed fit (EE). Whether you have a wider foot or prefer more room in your boots, you have the ability to adjust the size as needed.
The main difference between our Unlined and Lined boots is waterproofness. The Lined boots are built from a two-part system that features premium waterproof leather on the outside, and our innovative waterproof bootie on the inside. The Unlined boots feature the same waterproof leather, but are fully unlined on the inside to allow for maximum breathability and a lighter weight experience. They are still highly water-resistant, but not fully waterproof like our Lined boots.
While our Unlined boots feature a premium waterproof leather build, they do not have our innovative waterproof membrane on the inside—making the Unlined boot highly water-resistant, but not fully waterproof.
Unlined boots offer more breathability and are lighter weight than our Lined boots. Though they are not fully waterproof, they are still highly water-resistant and can handle light exposure to moisture and mud. They’re best used in hot, humid weather where comfort and breathability are essential.
