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.
Now that everything is finally done and good to go - I ordered the trailer in March but didn't get it until May - I will have to say that its a great trailer. In my opinion, yeah, it is very expensive but the trailer is made with good material. You get what you pay for....
Here's some tips -
Cons? I have a few, if you've visited the Rack and Roll website before they have a video of this woman who seems to have no problem breaking the trailer down. When I did it, I had lot of trouble removing the pin that connected the tongue to the trailer, I also had trouble removing the pins that connected the wheels and the shock absorber to the main trailer although it wasn't quite as bad as the tongue and trailer. There are locks that connect the tongue to the trailer and the wheels and shock absorber to the trailer. Those were a nightmare to remove, you have to push down on the handles really, really hard to unlock them. Yesterday, it took me about 30-40 minutes to put it all together because of the lock and pin issue I mentioned earlier. It almost seems like the holes on the trailer are just a tad bit too small for the pin and yes, I made sure they were aligned properly. On the storage side of things - the license plate doesn't quite align to the pre-existing holes on the trailer so I had to use zip ties to attach them - what does that have to do with storage? Well - if you store the trailer upright - when you attach the license plate its about ankle height so if you're not looking where you're going you can easily scrape your ankle/leg against it. And yes, I definitely emailed Rack and Roll about this. We'll see what they say.
