The Footprint King Foam Flat Insoles are 3mm of flat King foam designed to maximize impact-absorption in cupsole and vulcanized shoes. King Foam Orthotics from Footprint insoles appear to perform magic. Under moderate pressure (your bodyweight) they are soft and spongy, but under high-impact (when you jump), they tense up to absorb more impact. Staying comfortable and skating longer are one in the same. These insoles help to eliminate feet soreness and fatigue that can lead to injuries by molding to your foot, giving you a custom fit and feel. So whether you're skating big gaps or just techy stuff around the park, these insoles are a good idea to keep your feet comfortable and ultimately you on your board longer.

** breaking them in** 
It can take up to 5 days to break in the arch if you have flat feet. Although it can feel awkward or uncomfortable at first if you have never had orthotics, once they fully break in, it will be heaven.
