i preform a foot pocket before i put it in the front of my boat, then put it in and suck more air out of it.
when you put it in, make sure the the front air chambers are not folded over so you can pump it up after your backband is adjusted.
pump it up till your knees are snug in the the thigh braces.
This usually works for me and keep messing with it.
I wear ghetoo booites by IR and they rock!!!
