Offering lightweight comfort,the Mizuno Wave Prophecy 4 Running Shoe is great for training and running activities.Its not a stability shoe at all but it kind of wants to be.The shoe brings the hallmark Mizuno firm ride to another level that nearly pushes the Wave Prophecy 4 from the neutral category into stability.As such,previous fans should find a familiar ride underfoot and an improved upper on top.Neutral runners who cannot tolerate extremely soft shoes should look here.This is primarily due to the extra stability and torque resistance that the Infinity wave provides.
