Spenco Comfort are thin, lightweight insoles that can replace the original sock liners of your dress or athletic shoes for a bit of added comfort. They're made of neoprene foam throughout. While these flat insoles provide some shock absorption, they don't have any arch support.
Pro A great sock liner replacement for a very affordable price
Spenco Comfort insoles are a great way to make your dress or athletic shoes more comfortable if you're not looking to cure any ankle or knee pain. They're made of neoprene foam, which provides some shock absorption and a lot of cushioning throughout the whole foot. There's an antibacterial surface, which helps your shoes smell fresh. They cost under $10, which is about five times cheaper than more orthotic, support-oriented insoles.
Pro Fits any footwear
These Spenco insoles have a very low profile, which makes them ideal for both dress and athletic shoes or other tight-fitting shoes. They can fit over the original sock liner of your shoes without a problem, so you don't have to tear the original sock liner out as you would with more support-oriented insoles. They can be trimmed to fit any shoe perfectly.
Pro Can be placed over customer orthotics to provide more cushioning
The Spenco Comfort insoles are uniformly thin and they don't change the shape of what's underneath them. Custom orthotics tend to be hard (for good reason), so if you want to make them more comfortable, the Spenco insoles might be a good option.
Con Wears out faster than hard, supportive insoles
Because they are so thin, these insoles might wear out faster than the harder, more supportive insoles. Some users have said they last for a few months, but some have mentioned a whole year in durability. It probably depends on how often you use these, but don't expect them to last a lifetime. These Spenco insoles are very reasonably priced, so replacing them wouldn't be a major setback for most people.
