    Yes, I have.

    They are okay, but I prefer Sorbothane.

    If you want to try those, buy one size larger than you need. Unequal's foot insoles run small.

    What did you like about the Sorbothane over the Unequal footbeds?

    Do they add alot of weight? Sorbothane has alot of mass, do they weigh more than the Unequal footbeds?

    So, they are bulletproof? Why does an insole need kevlar, to keep it from tearing?

    Since I now go barefoot as much as I can, I have healthy feet and the regular insoles with my shoes work just fine.

    Sorbothane has been in insole business much longer, so there are many more products to fit your needs. They come in various thicknesses, durometer and shape. Some "Air Sorbos" are the most cushiony insoles I have ever worn.

    Unequal's Kevlar products tend to be more rigid, and this has its own benefits.

    Both add significant weight. Shock absorption advantage goes to Sorbothane.

    Kevlar is a great shock absorber.

    I don't think these products are designed to stop bullets, just like the old ProStaff isn't going to stop bullets.

    My custom orthotics are made with Kevlar. As hard as a tennis racquet.

    I guess I'm mostly familiar with Kevlar tennis string and Kevlar weaved into a fabric. It is extremely hard to cut or tear, but I didn't realize it was good at absorbing shock.

    Well I think it is good at absorbing shock considering that they make bullet proof vests out of it.

    I thought the advantage of Kevlar in a vest is that it doesn't tear and let the bullet through and is very strong for the weight. If you get shot wearing a thin vest, you're going to be bruised unless you have a trauma plate under the impact point.

    I'm not certain that's the same sort of shock absorption we expect with a footbed that flexes and dissipates impact given I don't have any really pointy pressure points on the bottom of my feet. I guess it won't tear or stretch.

    Have you tried the Superfeet Orange?

    Good support and with a thin footpad under the forefoot and a thicker heel cup they provide reasonable cushioning as well.

    [Kevlar can be quite flexible if thin. An example is Kevlar tennis strings. Not sure you need Kevlar for the supporting material unless you have a history of breaking the plastic inserts in Superfeet products.]
