(I was looking online for someone with a similar experience and found your post. Not the same situation, but I thought I would share my story in case it helps anyone out...)
After years of waiting I finally was able to get a pair of IR 8111s. I was reading online about ways to break them in, and somebody suggested getting them really wet, and then wearing them until they dried out.
So, with this in mind I decided to go hiking along a local creek, get them wet, and accelerate the process. It was warm, and I decided to do some swimming with the boots on. DO NOT DO THIS. The cork part on one of the boots, right underneath the leather sole (near the arch) basically cracked length-wise. The stitching inside the boot also seems to have loosened - I guess this was due to the swelling of the leather.I believe they are still wearable and will be okay as I continue to break them in, but I will probably need to get them repaired over time.
Also, if I were to do things over, I WOULD NOT PURCHASE THESE BOOTS FROM EBAY OR SIMILAR UNAUTHORIZED DEALER. As many have said, the sizing on these boots is wacky. I bought a pair from Ebay, and after several weeks decided they were too big. Since I couldn't return them, I had to sell on Ebay. I then bought a half-size smaller, and had the water issue. Had purchased them from a local dealer I could have returned them because I do think it is ultimately a quality issue. Also, I think I could go another half-size smaller - but am going to wait until I have more time to break them in. If these don't work, I am going to spend the money, pay full price, and get them from a local RW store.
