Karhu Fast Fulcrum_Ride Running Shoe Review

mens-karhu-fast-fulcrum_ride-running-shoeThe Karhu Fast Fulcrum_Ride road running shoe is scheduled to hit stores in the United States on February of 2011, but you can get these hot new shoes now on  The Internet spreads across oceans.  If you haven’t heard of Karhu before, it’s probably because they are a Finnish company, but they have been producing running shoes in Europe for over 100 years.  Karhu has a rich history in running shoes.  After WWII they sold their 3 stripes trademark to a little known German brand named Adidas for the equivalent of 1600 Euros today and 2 bottles of whiskey.  That better have been some good whiskey.  In the 1980s Karhu sold off their outdoor shoe division to Merrell.  Karhu is now back with its new fulcrum technology and bringing it to its new running shoe line.

The patented fulcrum technology they say is, “independently tested and proven, collaborates with the foot to convert your body’s natural energy into forward motion.”  Much like a fulcrum would but with collaboration with your body.  The technology is located in the sole of the shoe.  The fulcrum is more efficient with its lower pronation angle and velocity because it allows for appropriate pronation during the gait cycle.  The center of pressure moves along it’s natural path vertically from the heel to the toes without interruption.  Traditional running shoes transfer pronation energy from side to side.  The fulcrum also allows for more balance because it is naturally centered which accelerates the transition, the most unbalanced portion of your stride.  Traditional running shoes with flat cushioning and vertical posting can create braking and angular forces.  The fulcrum keeps you moving forward with less vertical oscillation.  Stop wasting energy on oscillating anywhere but forward, unless you’re running up stairs or something.

The Karhu Fast Fulcrum_Ride is a neutral shoe built for performance; that’s why its named “fast.”  The Fast Fulcrum_Ride is womens-karhu-fast-fulcrum_ride-running-shoes1able to transition pressure to energy.  The body’s nerve signals anticipate contact with the ground at a natural heel strike, and because of the fulcrum, the force of the impact is distributed evenly.  The activation leads to forward movement, following the body’s natural inclination.  The mid-foot is fully loaded and the body pivots over the fulcrum.  The maximum horizontal velocity is applied in a final push off the fulcrum, driving the body forward.  It’s just science.

The new Fast Fulcrum_Ride are great for flat footed runners.  The fit is true to size, with a narrow and low profile for speed.  However, they feel like they may not be as durable as other running shoes so the Fast Fulcrum_Ride may be best kept for race day.  The cushioning is great but the amount of padding seems unnecessary for a performance shoe.  The extra padding makes the shoe heavier, especially if it gets wet from rain or sweat.

It’s an interesting new concept and you can feel the difference when you run.  Check out if the fulcrum technology fits you.  It could be a fast ride.
