James, Thank you for the additional information.
I believe Proofide contains neatsfoot oil, which breaks down the leather fibers. We don't recommend it, because it tends to do what you describe: Suddenly softens the leather and then has it break down completely. I haven't used Proofide, so I don't know whether it affects the leather of Brooks saddles (which tends to be harder) than the higher-quality leather of the Berthoud saddles differently. We sell Obenauf's Leather Preservative instead, which just conditions and waterproofs the leather without softening it.
