Scott and Don review the Karhu Flow Trail.  The shoe proves to be a strong performer on and off the trail.  At 9.0 oz and a 2.5mm drop the shoe satisfies the minimalists requirements.   Bidirectional lugs for trail traction on the up and downhill side of the moutain.  The upper sports an airy mesh on the top with the lower 1/3 a solid material to hold out unwanted debri and water.   Using the grading TRN grading scale of 4-37 kokopellis the Karhu Flow Trail earns a 34.
