The Carbon insoles are Superfeet's lighest and thinnest model. They offer stability while racing and touring without weighing you down or squashing your performance fit. Made with carbon fiber and ultralight foam, the insoles help keep your heel in place while providing arch support for medium to high arches. They also add a little insulation between your foot and the snow.
Ultralight and thin construction is great for fast travel.
Holes cut in the forefoot adds some breathability.
I have size 42 alien 3.0s and I'm looking to alleviate heel slip on the uphill. Would insoles like these help? Also what size insole should I be looking at for a 42? Thanks
Thanks for reaching out, Chris. They would be a good first step to help alleviate heel slip so long as they match your arch appropriately. The "D" size would be the best bet. For more potential solutions to fix your problem, please click here.
Five stars for way more support than a stock flimsy footbed and at way less cost than a custom molded footbed. But minus a star for not being much lighter: 2.7 oz per pair when trimmed down to a size 26 as compared to 3.8 oz for a custom footbed with full posting. (I suspect the “carbon” in the model name refers only to the color!) So four stars overall.
I bought them on the idea of saving a bit of weight with a lower profile to fit within the low curvature of the RC1 heel cup. Turned out my boot guy was able to shave down my custom footbeds to wafer thinness in the heel, for a lower profile than even these Superfeet. So the Superfeet insoles are now in my xc skate boots, where they’re working out quite well.
