I was just reading this thread. Its funny that I use to wear the Burton Hails and would experience foot pain. I switched out the footbed and put in Superfeet but still had some pain. This year I purchased some Nike Kaijus. Took the Superfeet out of my Hails and into the Kaijus. Kaijus pack out more than desired, giving me heel lift, but didn't have the footpain. Decided to Frankenboot and put the Hail boot liner (which didn't pack out as much) into the Kaijus w/ the Superfeet. This weekend = The Return of Foot Pain.
Gonna put the Nike liner back in again, tighten up the liners a bit more (originally I didn't have them tight enough) and see what happens
