Here are the SW Motech footrests for the Ten...
The plane on which the footrests mount (red line) mean they stick out and further from the bike making the riding position much less cramp (standing or sitting). You can also see how much bigger the surface area is. Under the rubber is a decent serrated surface which is plenty grippy enough in wet/mud.
Mine are mounted in the lower position. As you can see from the picture below, it makes a big difference.
