Our Verdict
Nike Pegasus 42
ASICS GEL-CUMULUS 28
The ASICS GEL-CUMULUS 28 and Nike Pegasus 42 are both classic daily trainers, but they perform slightly differently. The ASICS is much lighter, with significantly more cushioning and protection overall. The Nike is firmer with more groundfeel and better responsiveness, though neither shoe is especially lively by modern standards. The ASICS is the better pick if you want more protection, while the Pegasus 42 makes more sense if you prefer a firmer ride.
