Karhu Fluid 3 Fulcrum
The draw: Cushioned but not clumsy
At 10 ounces for a size 9 men’s shoe, the Fluid 3 is substantial. Its robustly cushioned sole absorbs impact with the ground, but unlike many trainers of similar weight it allows the runner to completely control his or her stride. The heel is low compared to the forefoot, and as a result the shoe skips from contact to launch without the feeling of interruption. Fit is moderately snug, and the upper softly cradles the foot—this is a seriously comfortable shoe.
