Pro Specs Introduces the Marathon Series
With 3500 miles and 51/2 million footsteps of a grueling cross U.S.A. run as its testing ground, the new Specs Marathon Series has proven itself for durability, support and comfort. Engineered for long distance running, these shoes have conquered 130 degree desert heat, traversed the ominous Rockies and splashed through torrential rain and hailstorms intact.
The Specs Marathons: The running shoes that will conquer the distance, not let the distance conquer you ...
The Marathoners feature:
(1 ) The "Munich": Specs own "Track 80" outsole with its all terrain gripper design.
(2) The "Montreal": Custom engineered to fit all insteps in comfort.
(3) The "Athens": Light as a feather with mudguard outsole for maximum spring.
(4) The "Innsbruck": Unsurpassed flexibility and durability with unique poly outsole.
The Specs Marathoners are shoes designed by serious runners for people who take running seriously.
