Salomon Aero Blaze 4

Who Are Salomon Aero Blaze 4 For?

The Aero Blaze 4 is a neutral daily trainer for recreational runners who want one shoe to cover most of their weekly mileage, from steady base runs to the occasional pickup. It suits runners with efficient enough form to enjoy a moderate stack rather than those chasing plush, max-cushion recovery or dedicated carbon-plated racing. Think of it as a versatile workhorse, not a specialist.

Feelings and Experience

Underfoot the beaded optiFOAM² reads soft-but-firm: there's a lively bounce when you press into a faster pace, but it stays composed and never feels mushy or dead. Transitions are smooth and predictable, with decent ground feel for a trainer of this stack. The trade-off is fit — the version 4 upper hugs securely but runs somewhat narrow, so wide-footed runners should size and try carefully.

Performance Specs

• Drop: 8mm heel-to-toe offset — a moderate slope that balances heel comfort with forefoot engagement.

• Cushioning: Moderate — Salomon's optiFOAM² beaded TPU, protective without being max-stack plush.

• Responsiveness: Above-average — resilient TPO bounce from the foam alone, no plate.

• Stability: Neutral, moderately stable — a wide-enough platform for confident daily miles, no added pronation control.

• Pace: Optimal for 5:00–5:45 min/km (8:03–9:15 min/mile) — its uptempo daily-trainer sweet spot.

Best Distances and Maximum Speed

It excels at 10K, half marathon, and marathon efforts, plus easy and long training runs, with the half being its natural sweet spot. Push the pace and the foam works best down to roughly 4:45 min/km (7:39 min/mile); below that a lighter racer serves better.

Technologies and Materials

The midsole is Salomon's optiFOAM² beaded TPU, a resilient bouncy foam that runs entirely plateless — there is no carbon or composite plate here. The version 4 update brings an all-new engineered mesh upper with 5D print overlays for breathability and lockdown. It weighs about 226 g in men's US 9 on a 36 mm heel / 28 mm forefoot stack.
