Great shoes. People have told me that like most Chinese boots, they stink of old rotten sweat in hot weather, but that wasn't the case in my case. The so-called "air cooling" must work, because I can't detect any smell. and I have a big German nose that catches almost every smell! I highly recommend them. The only downside was that I wish they were 1/2 sizes over 12" when I bought them, but my new shoes ended up having a large forefoot with a wider fit!
