Ideally they would replace the manufacturers insert, boostedvan. By removing the original insert you give the new insert a neutral platform to rest on, you may also find that leaving the original insert in the shoe reduces the internal volume too much. That being said, everyone's foot is different, and you might find it works for you to leave the original footbed in there. It's a bit of trial and error to find what works best for you. ~ Ben
Hi, do these replace the boot manufacturer's sole insert, or sit on top of it? Cheers
