MixedTen days in, the Metaspeed Ray feels like a lighter but less stable Endorphin Elite 2.

PositiveA strong buy: marshmallow-soft and astonishingly light, and he ran his 3 km ekiden leg 47 s faster than the previous year, a PB at 53. The outsole wore as if he'd run a full marathon after only 3 km, and the instability gave him sore abs for three days. Keep it for very special races.

NegativeUnder 120 g and feels like nothing, with soft foam and surprisingly durable thin rubber after a full marathon. But it was wobbly even at 3:35/km, and he cramped after 20 km at Kobe. As he faded, the softness turned into bouncing up rather than forward, so for him it's a half-marathon-and-under shoe.

MixedRidiculously good at race pace, sinking into soft foam that gives the energy straight back. A weapon on the right feet, but not for most people: recovery jogs felt wobbly, one tester wouldn't recommend it to mid-pack marathoners, and another tester's pair looked heavily worn at 52 mi.
