My Speedmistress was fitted with runningboards by the previous owner and felt a bit wierd at first but now that I'm used to them I can't complain at all.
I did a 560 kilometre ride last Sunday and only after the first 400 K did my bum start to get a bit sore. I was sitting on 110/120 kph occasionally 130 and the feet/legs were happy. I haven't tried the rear peg alternating riding style yet but must give it a go next long journey I take , more for the bum/back relief than anything else. (you learn something everyday)
If you get the chance to take a ride on a Speedy with boards before you commit to buying some maybe you will get an idea of how they feel.
I think that if your feet are giving you problems these will help more than hinder.
