I have strolz custom foam liners and superfeet footbeds. They changed my life!!!! I used to get shin bang from bumps and landing airs, and my feet would cramp. Not anymore, The liners that come in your boots pack out in about 30 days if you ski hard, the custom foam liners last about 300 days with no change in the density of the foam. They ROCK --- worth the money, but put them in a boot you like, becasue when the shell wears out you can put them into the new boot as long as it is the same make and model.
