Replying to Boot modification?

I've got some 1080 guns which I love for everything, but could use a lil more coushin for the pushin in the park. I already added some foam ovals to the toes and they worked awesome last season, but I wouldn't mind a cushier tounge since the one it has is basically rock hard foam... anyone done any kinda modifications to they boots? The flex is perfect for what I do and they are nice and light and all and they still fit so I have no plans of getting rid of them any time soon. I've also considered trying using different liners, but I'm worried that might sacrifice a fair bit of their performance out of the park because right now they feel amazing for carving and stuff. I think a differen't liner could be sweet though...??
