clip in pedals for mirage drive

I like this idea. Yes, I am a full time road and mt. biker...but after about 3 to 4 hours of 2.5 to 3 mph slow trolling in Baja this summer, every trip (12 trips) was the same. SORE upper leg muscles, just below my butt. My butt and back were never sore. And the sandals look to be about the same as what I use now, without the cleats.
   When I get an extra $60.00, I will give it a try....thanks, Ron
