Our Verdict
ASICS GEL-CUMULUS 28
ASICS GT-1000 15
The ASICS GT-1000 15 and ASICS GEL-CUMULUS 28 are both daily trainers from ASICS, but they're intended for very different runners. The GT-1000 15 is the dedicated, entry-level support shoe, providing impressive support for those who struggle with excessive overpronation thanks to its 3D GUIDANCE SYSTEM. The CUMULUS 28 is the no-nonsense daily trainer, delivering more protection, more versatility, and, despite lacking a dedicated guidance system, more support overall. The CUMULUS 28 retails far above the GT-1000 15, however, making it the more premium pick.
