I've got the Hein Gerike version of the TXC Infinity and they've been totally waterproof for years.
I had a pair of these too until a couple of years ago. They endured 14 years of motorcycling without leaking but we’re otherwise worn out otherwise I’d still have them. Fantastic boots. I now have some RST boots, can’t remember what they’re called, but they’re waterproof so far - one year in. Having said that, I haven’t ridden many miles this year.
