Adidas Adizero Evo SL vs Asics Magic Speed 4:
Which to Choose

The sharpest dividing line is the plate. The Magic Speed 4 carries a full-length carbon plate that creates a stiff, rockered forward roll — the kind of geometry that compounds in efficiency over longer distances, particularly from the half marathon through the marathon. The Evo SL has no plate at all; its Lightstrike Pro foam (a PEBA-class compound) handles energy return on its own, producing a softer, bouncier rebound rather than a rolling push. Because PEBA outperforms EVA-based foams in raw snap and resilience, the Evo SL manages to match the Magic Speed 4's responsiveness rating without a plate — but the character of that responsiveness is genuinely different: springy and forgiving on the Evo SL, firmer and more mechanically purposeful on the Magic Speed 4.

Weight is a real separator. The Evo SL is meaningfully lighter than the Magic Speed 4, a gap you notice at the end of a hard interval session or late in a race. The 1mm drop difference (6mm vs 7mm) is minor and unlikely to be felt, though both shoes share a similar midfoot-forward geometry and neither suits a heavy heel-striker well.

Distance range is where the split becomes clearest. The Evo SL excels from 5K through the half marathon, with the 10K as its true sweet spot and an optimal pace band starting around 3:45 min/km — it's built for shorter, sharper efforts. The Magic Speed 4 is the one you reach for from the 10K through the full marathon, with the half as its sweet spot and an efficiency window that stretches further into longer race durations; the carbon plate justifies itself precisely because the compounding efficiency advantage grows the farther you run. Both shoes feel slightly awkward at true easy-jog paces — they want a committed stride to feel at home — and neither offers meaningful pronation control, so moderate overpronators should look elsewhere.
