The heel caps and arch support are shallower than any other Superfeet insole, but the basic construction is the same. This allows the Carbon insoles to fit in a wider variety of shoes, and can even fit some dress shoes (if they have removable insoles). The Carbon insoles stabilize and support your feet by keeping your heel in position, and letting the heel caps absorb part of the shock as you're running. This reduces stress on your feet, ankles and knees, so you'll be more comfortable instantly (if you get the right size).
The Superfeet Carbons fit in a wide range of tight-fitting sports shoes, like cleats and running shoes. They're lightweight and breathable, and provide support, balance and comfort.
There are perforations under the midfoot and forefoot. This helps reduce weight and improve breathability of your insoles, which is especially important if you tend to sweat a lot.
Superfeet insoles can not be machine-washed. You need to hand-wash them with soap and water, and allow them to air-dry. If you do so, they will last for up to 12 months or 500 miles, whichever comes first.
The perforations improve ventilation, and the closed-cell foam has antimicrobial treatment, which discourages bacterial growth and helps reduce odor. The closed-cell foam also means that there are no pores in which bacteria could grow.
Superfeet recommend wearing their insoles a few hours at a time for the first week, so your feet get a chance to get used to them. However, many users have stated that they instantly felt a positive difference, and didn't need aay adjusting time. Still, you should be careful to pick the correct size and arch height for your feet, and allow some time before returning them.
Superfeet Greens are high volume insoles, which means they take up more space in the shoes. This is ideal if you have loose-fitting shoes, or if you have narrow feet. They improve balance, provide comfort and support for your feet.
These insoles have 3/4-length polypropylene heel caps with a deep heel pocket. This stabilizes feet inside shoes, by keeping your feet correctly aligned as you move.
The Superfeet Greens contour your footstep, providing support from all sides. The rockered bottoms and cut-outs allow for natural shock absorption. The top layer is made of closed-cell foam, which provides cushioning.

They're treated with Agion, and antimicrobial treatment, which discourages bacterial growth and helps reduce odor. The top layer is closed-cell foam, so there are no pores in which bacteria could grow.
Depending on the quality and type of shoe you pair Superfeet Greens with, moisture wicking can be a problem. The closed-cell foam in these insoles does not absorb moisture, so If you sweat a lot you might want to try other options.
