The All-New Upper
Taking a look at the new Powerstrap R2 Aeroweave shoes at Eurobike in Germany, the upper is made of a highly-breathable and advanced woven fabric not yet used in cycling footwear. The lightweight nylon fibers are interfaced with filaments of thermoplastic polymer – a blend of threads that create an open, net-like pattern.
Riders’ socks are visible through through the shoe that will be only available in black. Fizik say the material is malleable, moving with the fitment system to effectively cradle the foot.
“But its structure results in a tenacity so strong that it delivers the support and containment required for a racing shoe at the highest level of performance,” said a Fizik rep at the show.
‘Stiffest Sole In Fizik Range’
To the all-important ‘table test’ and the Aeroweave features a super-stiff feeling sole.
“The all-new R2 outsole is engineered with a carbon fiber layup that both saves weight and delivers a dramatically increased stiffness,” said a Fizik rep. “This ensures efficient and positive drive from the rider’s legs to the pedals. With its index rating of 10, the R2 is the stiffest outsole in the fizik range.”
The R2 underside also combines a wide vent inlet and deep internal channel for extra airflow.
Setback Cleat Position
Cleat holes on the shoe are positioned slightly rear-wards, Fizik say this optimise pedalling efficiency and reduces knee compression when in aggressive, aero riding positions.
