Salomon Aero Glide 4 vs Salomon Aero Blaze 4:
Which to Choose

The clearest divide is stack and cushioning. The Aero Glide 4 sits on a 43mm heel / 32mm forefoot platform with maximum cushioning, while the Aero Blaze 4 runs lower at 36mm heel / 28mm forefoot with moderate cushioning — that's roughly 7mm less foam underfoot, which shows up directly in feel and weight. The Glide 4 weighs 255g (men's US 9) against the Blaze 4's 226g, so the Blaze is meaningfully lighter and quicker on the foot. Drop differs too: the Glide's 11mm offset is more heel-friendly and easier on the calves, while the Blaze's 8mm sits more neutral and asks a bit more of the forefoot. The foams also differ despite sharing the optiFOAM² name — the Glide uses a supercritical eTPU that lands tall, soft, and springy with a genuine toe-off pop and a strong ~72–73% energy return, whereas the Blaze uses a beaded TPU that reads soft-but-firm, composed, and gives noticeably better ground feel. Stability tips slightly toward the Blaze (4/6 vs 3/6): its lower, wider-enough base feels planted for daily miles, while the Glide's tall, narrowish platform can feel a touch tippy at very slow, plodding paces even though it settles beautifully once you find a rhythm. On use case, the Glide's sweet spot is the long run and protective easy mileage that drifts into moderate tempo (optimal ~4:45–5:45 min/km, effective down to ~4:30), while the Blaze's natural home is the half and versatile daily running with the occasional pickup (optimal ~5:00–5:45 min/km, workable to ~4:45). Two things they genuinely share: both are entirely plateless, and both run somewhat narrow through the engineered-mesh upper, so wide-footed runners should size carefully either way.
