I use the blues in my snowboard boots because I also do not have high arches. I decided this past winter to give the greens a shot, and while they were quite comfortable, the arch is a little higher because there is also a slightly higher heel cup. I wound up switching back to the blues because they compromised the heel retention system in my boot and my foot slid up more. So, while I would recommend the greens for high-impact activities for some people, keep in mind that they do take up more room in the heel than the blues. And if you have flat feet, I would stick to the blues.
