Hello, how may I help you?
Hi, I am interested in knowing if the Calvin Klein boots are waterproof.
Let me find out for you.

We have both waterproof and non-waterproof ones. One way to tell is that there is a guarantee when you make the purchase. Most are waterproof.
Okay. That helps.
Can I help you with anything else?
That was my only question for today. I will go ahead and purchase them.
Have a good day. Enjoy the boots.
