I have two of my three pair of Lacross boots that now have leaks. One is my fault, as I cut it on barbed wire crossing a fence. The others are my 2 year old Alfa-Burley's that have cracked at the junction of the ankle, and the upper. I'm not ready to retire two pair of $130.00 boots. Whats the BEST patch for these??? I know silicone will NOT stick, and they are not real rubber, so i wouldn't think a rubber tire patch would stick either. But I don't know that.
