Burton's isn't the best, that's fair. I never had an issue with mine, but I know a couple people that have. It is far less common than hearing people with Union toe strap problems though.
Good luck with the Infidels, the wings aren't really all that useful on the outside, but it is still my favorite binding from them ever. Using 30% short glass in that 2 piece frame was money. Dumbest idea to get rid of it.
Burton's isn't the best is an understatement.....by far the most useless toe caps I have ever had and I was using them with a pair of Burton boots. My Unions ( both Atlas and Contact pro's) work great with Burton boots....figure that one out......
