This product is everything I'd hoped it would be:  it's very "grippy" stays put because of the silicone, very cushy, and wide enough to distribute the pressure of the strap, and easy to put on.  Two thumb up.  Had an unusual reaction the first time I wore them, I developed a small blister along the edge of one of the pads.  It wasn't a friction burn as it wasn't red/irritated.  I thought that I might be allergic to silicone but I haven't had a problem with them since and I've worn them about five times.  I wouldn't let my reaction dissuade you from purchasing them, they are great.
