assistant: You're in the sweet spot for a carbon racer — 60 mi/wk gives you the volume to dial in a shoe, and your midfoot strike + 65kg frame mean you can handle the firm, responsive platforms these shoes demand. Before I narrow it down: **what's your cadence like, and have you raced in a super-shoe before?** That matters because the field splits into two camps — stride-focused (longer ground contact, softer compression) vs. cadence-driven (faster turnover, snappier plate feel). Your midfoot strike suggests you're probably cadence-oriented, but confirming helps me rule out the wrong shoe. In the meantime, here's what stands out from your options: **Puma Deviate Nitro Elite v4** — Lighter, firmer, more controlling than its predecessor. EDDBUD calls it "one of the lightest Puma racers ever" and notes it "wants you to pick up the cadence" — if you're a turnover runner, this is the one. Doctors of Running's Andrea found it firm but snappy, reminiscent of the SC Elite v3. At 170g it's competitive on weight, and the 8.0 mm drop is forgiving for a midfoot striker. Excellent expert reception. **Mizuno Hyperwarp Elite** — Snappy, versatile, and durable (150–250 mi is solid for a racer). The 3.5 mm drop is aggressive, but the moderate rocker and smooth transition smooth out the landing. EDDBUD praises it as "dependable, light, and versatile" with excellent grip and stability. Best if you want a do-it-all racer that handles threshold work too. **ASICS Metaspeed Sky Tokyo** — The softer, compression-driven option. Maximal cushioning (40/35 mm stack) and a lower 5.0 mm drop suit stride-focused runners better. If you're a longer-strided, smoother cadence runner, this could work — but EDDBUD's note suggests it's "less effective than the prior" version, so it's the riskier pick here. **What's your typical race cadence, and have you trained in a carbon racer before?**

assistant: **Alphafly 3** for your sub-3 marathon. You're a midfoot striker chasing a specific time goal on a single race day — the Alphafly's softer, more forgiving platform and superior durability matter more than the Vaporfly's raw lightness. Here's the split: The **Vaporfly 4** is a half-marathon-and-below shoe. It's 167g, snappy, and punishes lost form — which works brilliantly if you're running 5K-10K at full aggression. But Doctors of Running flags it as "best suited for 5K-10K rather than half/marathon distances," and FORDY RUNS explicitly calls it "definitely half marathon and below." At marathon pace over 26.2 miles, that aggressive rocker and thin stack (36/30mm) will tax your calf and midfoot more than you want when fatigue sets in around mile 18. The **Alphafly 3** is built for what you're doing. It's 198g (heavier, but that's cushioning, not dead weight), with a 40/32mm stack that gives you real protection. EDDBUD notes it's "more durable" than prior versions and "keeps improving with use" — crucial for a marathon where you'll log 15–20 miles in it during training. Ben Is Running calls it "very responsive and poppy" but emphasizes it "felt effortless at marathon pace during a 15 x 1K workout." The moderate rocker and softer ZoomX compression suit a midfoot striker better than the Vaporfly's aggressive geometry. The catch: the Alphafly begs you to land on the heel (EDDBUB: "begging you to land in the heel"). As a midfoot striker, you won't fight that — your natural landing will sit in the sweet spot between the forefoot pop and the heel cushioning. The Vaporfly, by contrast, is designed for forefoot strikers and will feel unstable underfoot for you. **Pick the Alphafly 3.** Save the Vaporfly for a 10K or half-marathon tune-up race if you want to test it, but for your sub-3 attempt, the Alphafly's durability, marathon-specific tuning, and forgiving platform are the right call.
