I paired the Talon Focus boots with the Flow NX2-RS binding and they've been really good so far. The Talon boots are by far the best made and most comfortable boots I've ever owned. Great fit with the dual boa and zero heal lift.
It takes a bit to get Flow bindings set up and bit more time to tweak them once you've had a chance to ride but they're well worth it in my opinion.
The Talon's definitely fit the bindings better than my Burton SLX and Thirty Two Focus but I was thinking that it would be a big difference, however, that's not the case.
