Highly recommended
Soles insert user for >4 years. Very comfortable with perfect amount of support. These thicker footbeds are perfect for work/urban boots for daily wear. I have them in all my favorite shoes/boots; they last 2-3x longer than footware themselves!

Great support
I have knee, ankle, and arch issues and so I wanted to add support to my shoes. These are so incredibly comfortable. When I first put them on, I felt like I was walking on plush springs. They lose their spring-y-ness after a couple of weeks, once they are broken in, but they are still comfortable as the longer you wear them, the more they mold to your feet. They are pretty think, so you definitely have to be able to take out your shoe inserts, as opposed to adding them on top. I wear them with Toms shoes a lot, but unfortunately they get kind of stinky when I don't wear socks :( That's my problem though! I highly recommend these, as did my physical therapist after my knee surgery.

THE BEST HIKING INNERSOLES ON THE MARLET!
The best innersoles for long distance hiking I have ever worn. I will not be without them for comfort and support in the future!

Great insole for the flatfooted!
These insoles work as advertised. They'll mold to your feet over time or you can speed up the process and bake them to your foot. But be warned, they add significant height to your heel placement in whatever shoes/boots you put them in. This may cause your footwear to no longer fit as well. They reduced my overall feet fatigue. However, I lost some ankle support as my feet no longer sat as deeply into the boots. They ended up working better in trail runners where extra ankle support wasn't an issue.

Good support
These footbeds provide good support and are thick enough to improve fit in some cases. The "moldability" feature seemed a bit overrated though, and I found that a couple days of wear seemed to do a better job.
