There were 2 pads that I tried. One, that I bought, a Cavalo Memory Foam Pad, and the 2nd was one that belongs to a friend out at the barn, a Fleeceworks. I am glad I tried it before I spent the money on it, because I was not impressed at all.
I find they work just like the Gel Pads.....where you put pressure down on an area, and the material moves away from the pressure, allowing pressure points.
The Fleeceworks, was super thick, and when I pressed down on it with my fingers, it didn't compress very much...it was a stiffish material. I thought "Hey, I like this!" but when I used it, it didn't hold it's consistancy at all when the memory foam heated up during use, it compressed and got thinner. When I was finished with my ride, and I removed the pad, you could see the pressure points that my saddle caused.
When the pad cooled off, it went back to its origional thickness and hardened up.
So, I don't think it works. If I were to spend the money, I'd look for a pad that dispurses that pressure, instead of running away from it. Like Thinline.
I got the same results from the Cavalo Pad - I got rid of that pad, that pad is garbage as far as I am concerned. That pad ended up compressing permenantly.
