I've been rocking the Power Wrap in both Full Tilts and K2 Dispatch touring boots and they add significant performance to both boots. Even compared to the stock intuitions in Full Tilts I get a snugger fit and better power transmission. For a bit more comfort and a slightly softer option, I also use the Intuition Alpine Liner, which has the same fit properties but doesn't stiffen the boot so much.
For those that care about these things, they are also crazy warm, but I'm not generally someone who gets cold feet. It's a bit weird cramming the wrap liner in a boot designed for a tongue at first, but it makes my boots feel so much better when I do.
I have fairly narrow feet, but with the Alpine/Power Wraps in, even the Dispatch, which I use for touring and has a 100mm last and a fair bit of volume, feels great. - @Twig
