These boots are not waterproof. Since they are leather they will be water resistant, and you can apply a waterproof agent to them.
These boots require waterproofing them yourself. This is not hard and I would highly recommend Obenaufs Heavy Duty LP.|The only boots that come waterproof use a Goretex liner, these liners tend to be hot, and once the liner breaks down from use the boots will no longer be waterproof. |Boots like the Summit that you waterproof yourself will last much longer provided you take care of them.
