*Note: My feet are very strange and particular to certain shoes/insoles, etc. In fact, ALL feet are different, so what might work/not work for me may work for someone else. Use whatever feels right for you.
Sorbothane®, a one-of-a-kind visco-elastic polymer, was first introduced in 1982. Primary applications included the development of shock absorbing insoles for the athletic and orthopedic markets. Since its introduction Sorbothane® has been used in many varied energy absorbing product categories. Sorbothane® Inc. engineers supplied the NASA design team with a unique Sorbothane® isolator to protect shuttle cameras during launch. The Liberty Bell was successfully moved using specially designed Sorbothane® isolators. When Wilson® Sporting Goods needed a superior shock absorber for their new line of high-tech baseball gloves, they turned to Sorbothane®. Most recently, engineers have devised a series of colossal "ball-in-box" Sorbothane® dampers designed to dissipate wind energy in the new Air Force memorial.
Sorbothane® is the only insoles material that absorbs up to 94.7% of impact shock; and unlike standard insoles, which can bottom out and lose effectiveness, Sorbothane® Insoles retain their support and comfort, month after month. Lightweight and durable, they also breathe, which makes for a much cooler insole.

Sorbothane® SorboAir® Insole

My initial thoughts:
* Oooo, they're squishy!
* They seem really sturdy, compared to other gel insoles.
* They actually fit in my shoes!
Now for the running test...
The first thing I noticed once I slipped these insoles in my Brooks shoes was that they are a little thicker than my normal insoles. My feet felt more cramped and I had to loosen the laces quite a bit. No biggie, I thought. During the run, I couldn't really notice a difference comfort-wise, however, towards the end of three miles I did notice that my feet were getting a little numb. Are my shoes still too tight? I loosened the laces some more and kept going, but my feet didn't feel any better. Very strange.
The next night I tried the Ultra Work Sport™insoles and had that exact same problem: numb feet.
So I decided to just try these insoles in my regular walking shoes and guess what? No numb feet! In fact, my feet feel amazing using these insoles for walking or standing for long periods of time. The cushion is just right and my feet don't feel as fatigued as they do with the normal insoles shoes come with. Now, I regularly use the Ultra Work Sport™insoles in my walking shoes because they are a tad bit thinner/lighter than the normal SorboAir® insoles.
