First, I agree with the other reviewer that mentioned that the pads slide around and doesn't stay in place. This is particularly evident if the bottom of your kayak isn't flat. The pads seem to slide towards the center of the kayak - if you have a flat bottomed boat - I don't think you'll have a problem. Don't get me wrong though - once you do a little footwork in your boat and get the pads positioned to your liking it will stay there as long as you have your heel on it.
As for the solution they've implemented to secure the heelpad in place for the waffle style foot pegs. I have one very important suggestion for you - do not attempt to install the footpad when you are already in the water in your kayak - you will be in danger of flipping yourself. Install the footpads on land outside of your kayak. It takes a little bit of maneuvering and crouching to get it in place but once its attached and you've tightened the nylon string that holds it together it stays in place.
Overall, the heel pads are great especially if you're paddling great distances. It takes a lot of stress off your heel and makes your paddling experience much more enjoyable.
