Do intuition liners shrink or expand each time they're heat molded, or do they return to some original thickness/size each time they're heated? Does heating act like a reset button or is there a limited amount of times a liner can be remolded?
It depends how much they have been used. If they have been skied in quite a bit then remoulding will probably do very little. It may feel a bit better for a day or two but will pack out again quickly. If the liners are newer you will have better results but don't expect a reheat to make them into new liners again.
