"The Supernova Sequence 4 features the most significant changes made since its 2008 introduction. The upper continues with the proven open mesh and welded microsuede overlays, but now employs an external TPU heel stabilizer to neutralize excess side-to-side motion. Though the midsole has the same basic setup, two changes improve its effectiveness: The FORMOTION unit has a more sculpted heel bevel, and the ProModerator has been upgraded to ProModerator+, in which the component is thicker and the ends have been rotated 90 degrees to shore up the sidewall in three dimensions. The outersole is still the familiar and effective carbon heel/blown rubber forefoot combination. For its combination of stability, cushioning, and value, the Supernova Sequence 4 earned honors as our Best Shoe in the Motion Stabilizing category."
