rocky boots unconditional warranty is a lie nelsonville, Ohio

I bought a pair of rocky ironclad boots in may. 2 months later I looked at the bottom of the boots, and part of the heel was peeling off. I returned them and they gave me another pair. 2 months later I looked at the heel again and the other side was peeling off. I called rocky boots and they said that their warranty was for 1 pair of boots only, and there is nothing they can do about it. Their warranty states that they have  6 month unconditional warranty. I have emailed them and no response. Buyer beware.
