Carnac cycling shoes are both legendary and mysterious.  Carnac was founded in 1949 and is a leader in international cycling shoe development.  They mystery surrounding the company comes from the fact that Carnac does very little advertising outside of the European cycling world (they only recently appeared on US Google searches) and due to the closely guarded secret of the Ergo Cut+, Carnac’s patented adjustable width bike shoe technology.

Another adaptability feature in Carnac triathlon shoes line is their patented sole stiffness variation achieved with the use of ‘sole stiffener bridges’.  This results in maximal power transfer.

Carnac Triathlon Shoes

Only three Carnac cycling shoes are currently available:

Carnac M7 This shoe has a 100% carbon sole and even comes with a replaceable heel pad. The Carnac M7 triathlon shoe also features an ergo sole insert which dampens vibration and provides increased foot stabilization inside the shoe.
Carnac Eclipse The Carnac Eclips has an upper composed of microfiber and neoprene. In keeping with Carnac’s heritage, this shoe has the Ergo Cut+ width adjusting feature. It also has the arch support strapping system and the MPS 5 injection rigid sole.
Carnac M1 The Carnac M1 is the budget Carnac triathlon shoe. It has fewer nice features, lesser quality components, less engineering and may not be as comfortable. Having said all that, its still a tremendous shoe and more than adequate for triathletes.
