Check out the following link to an Ed Burke article on the CTS site:
http://www.trainright.com/ctscafe/articles/edburke/energycost.htm
To summarise, Burke says adding 250 grams to the shoe/pedal combo per leg (500 grams total), will
increase the power required by 1.5 to 1.7 percent.
As for the shoe weights the original poster lists - I'm pretty sure the weight of the Nike shoe is
Nike's claimed weight for ONE shoe, while the Carnac weight is Carnac's weight for BOTH shoes. Like
every other component maker, shoe companies are nortorious for providing less than accurate weights.
Thanks,
Eric (who uses Carnac Quartz shoe and Time Equipe pedals!)
