Here is what Ergon has to say about the pedals:
A more efficient pedal. Ergon introduces the first flat pedal (or Contour Pedal as we call it) to provide an ergonomic and positive connection between bike and user. The first pedal designed with biomechanics and correct foot position in mind. Advantages are increased power transfer, more control and fewer hot spots and knee complaints.
The Ergon PC2 is the first non SPD-type pedal constructed with the ergonomic biomechanical demands of the user as a priority.
You can see how it would be difficult not to try these out... particularly for those of us who are SPD-cleat/shoe averse. No more knee pain? No more hot spots? Greater power transfer? These all sound like fabulous things to me.
The pedals come in two sizes (small - up to size US8.5/EU42 or large - minimum of US9/EU43), so in order to get the proper fit on the pedals, it's important to pay attention to the size of the pedal. The manufacturer states that these pedals are meant for commuting, touring, and general riding. I think that seems about right. For most people, I don't think these would use on a road bike or even necessarily hard-core mountain biking - but, who knows? Like me, you may be ready to give them a try.
Currently, the PC2's are set up on my interim road bike, the Soma. I've used them on many rides from just around town to 40+ mile training rides. They've gone on flat terrain, and up some not-so-fun climbs. I've mashed up hills and pedaled hard coming down the other side. The good news is, they've withstood (to date) the abuse I've put them through. Their exterior at first glance would cause me to think that they'd likely fall apart pretty quickly, but that has not been the case. The center piece has a kind of textured (almost sandpaper-like) substance that helps keep the shoe in place on the pedal. I do appreciate not having to worry about my foot slipping off the pedal (which is not always the case with some platform pedals).
I like that the pedals have reflectors on them for added visibility in the darker hours of evening rides. I also appreciate the inner stop piece that helps keep my foot in the right place on the pedal.
Foot numbness/pain and power transfer? I don't know that I noticed any improvements in these areas myself. I'm sure there's definitely some increase in stability if for no other reason than the width of the platform - which I suppose could assist with power (or at least feeling that way) on a ride. My foot numbness is still present though, which was disappointing. If it was minor numbness, I'd likely just let it slide, but I had a ride over the last couple of weeks during which my foot was so numb it had spread up my ankle completely so that I could not feel my foot or ankle at all. To be fair, since I'm still working out positioning on the Soma, I don't know that the pedals can take all the blame for this particular aspect, so that will be something to determine at a later point. I haven't had problems with hot spots on my feet prior to these pedals, so I cannot evaluate that particularly claim. However, I can say that they didn't cause hot spots, so that's definitely a positive.
Overall, I think the pedals work better than many I've tried - even dealing with the numb feet situation. I believe they'd be a great option for someone doing touring rides or commuters who prefer this style of pedal. For an individual who doesn't mind the bulky appearance and extra weight, I would put them on a list of possibilities for pedals.
Retail on these here in the U.S. is $79.95, but I have spotted a few deals in various locations online and in local stores. Discounts seem to be difficult to come by for these pedals, so if you spot one and are interested in giving them a try, I would snap it up. For a quality pedal, $80 seems to be about on par as far as costs go, and I've seen other platform pedals going at easily $100+/pair, so although it seems like a hefty price point, if the longevity is there, I don't think it's a completely ridiculous price point. Of course, the life of the pedals remains something to be seen.
As for me, I don't know if I'll continue to use them on my road bike over the long haul, but they've done their job so I can't complain too much. I think for future use they'll be relegated to a more city/upright-type bike, but I've appreciated the opportunity to use them and look forward to seeing how they hold up over the long-term.
