Harley Davidson Boot Quality Issues: Warranty Failure

I bought a pair of Harley Davidson boots and wore them five times during the second month. Unfortunately, the sole ended up coming apart. I asked for a refund or an exchange, but instead, they sent it for inspection and just glued it back together before giving it back to me. So, in the past month, I wore them two times, and once again, the sole fell apart. I've never seen a product this bad before, and even though it has a warranty, they're not offering any exchanges or refunds. This doesn't make the Harley brand look good. I'm not gonna make this mistake again and I'm not gonna buy their products anymore. I just wanted to let you know about this situation.
