There's a company in the states (Colorado) that makes shock mitigation flooring. They make them for the U.S. Navy Seals and a civilian version. I've tried both and they're great.
There website is
www.seashocks.com
The military version is more expensive and requires a dollap of glue at each corner an an edging material. The civilian version doesn't require a dap of glue as the bottom has a very tacky layer of stick high grade urethane.
I'm impressed. They sent me a version of their civilian sea shock (only comes in blue, the military grade only comes in grey). I went out in a rib and the mat didn't move around at all and was very comfortable and does what it says. It is newly released and is really a quality product.
They have an 800 number if you have any questions 1-866-SEASCHOC.
