Like most Superfeet insoles, the Berry has a deep heel cup where your heel would be kept in place. The extra support relieves foot, ankle and knee pain, especially if you're doing high-impact activities (such as running), or walking or standing for a long time. The Berry insoles have a slimmer heel and a shorter arch length, which makes them better suited for women.
The Superfeet Berry insoles are high to medium volume, which means they fill up more space. The Berry insoles provide support and comfort, and they're durable. This makes them ideal for loose-fitting shoes and people with narrow feet (unless your shoes are narrow as well).
The Superfeet Berry contour your footstep, providing support from all sides. The rockered bottoms and forefoot shock pads for natural shock absorption. The top layer is made of closed-cell propylene foam, which provides cushioning.
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.
Depending on the quality and type of shoe you pair these 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.
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.
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.
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.
