I've been running in the Mizuno Wave Inspires for several years and find them to be very good shoes for a lightweight (130-135 lbs) over-pronator like myself.  The model 13s feel a bit different from the 12s that I'd been wearing previously: they seem less stiff in the sole, and a bit wider up front in the toe box.  But they're still a good fit for me & hug the heel nice and snug like they should.  These shoes are well-designed, supportive for hard runs, and durable. Haven't yet tried a pair of the model 14s because the 13s were available on sale, so why not?  And, an extra bonus: I've also worn the Wave Inspires for basketball.  They work just fine, indoors or out -- no problems at all with the rapid twists & turns of a hoops game.
