I work in the electrical testing field and we sometimes use 15kV AC & DC test voltages Or higher. And these offer the protection I need and the water proof leather always comes in hand for those gulf coast storms. They’re a little heavy, but it’s due to the construction and durability of the boot.My husband loves the boots. He said he’s never worn a better work boot before.Great boots, but Foot ovens when working, could use some kind of ventilation.Very comfortable and look great.Comfortable and they have held up well.Boot has been great and is holding up nicely to daily wear. The break-in around the heel has taken quite a bit longer than the Red Wings I normally wear, but I hope this translates to a good long lifeWhat a great boot!Least amount of "break in" time I've had on boots.Ive only had them abiut a month though,so we'll see how long they last,and I'll write an update review.But so far...AWESOME!
