A pair of steel toe rubber boots suffered a small crack near the steel toe. Sad to see, was the best pair of boots I've owned. I would have never guessed that they would crack before me being an idiot and stepping near a nail putting it through the side on accident. I also bought a new pair of Terra work boots that I would like to seal and make them more resistant to water. I hate working all day outside with wet feet and try to avoid wearing rubber boots when possible. Another option I thought about buying is a neoprene boot liner, but a no leak solution sounds better.
