assistant: Before I recommend, I want to clarify one thing: for race day, are you looking for a dedicated carbon-plated racing flat to go fast, or a cushioned shoe you can also train in comfortably over the next few months? The reason I ask is that most first-time marathoners do better with a shoe they've already logged 50–100 training miles in — something that feels familiar on tired legs. Pure racers (like the Puma or Brooks cards I have) are built for speed at race pace, but they're firmer underfoot and have shorter foam life (~150–200 miles). A training-performance crossover gives you the same speed potential with more cushioning and durability for your build-up. Also, at 85 kg, stack height and midsole durability matter more than they do for lighter runners — you'll compress the foam more, so a shoe with robust cushioning (40mm+ stack) and a proven track record for heavier athletes will feel fresher at mile 20.

assistant: You're exactly right — pure racers are built for speed and durability at race pace, not comfort over 4.5 hours. At your weight and target pace, you need a shoe with robust cushioning that'll feel fresh at mile 20, not one that's optimized to be light and snappy. The **Mizuno Hyperwarp Pro** is your best bet here. It's dual-categorized as both a daily trainer and racer, but Doctors of Running calls it a "training-performance shoe rather than a pure racer" — which is exactly what you need. It has 46.0/40.5mm stack (the thickest in my data), a full-length carbon plate for efficiency without sacrificing comfort, and Andrea from Doctors of Running reports 100+ miles already with expectations well over 250–300. Believe in the Run notes it's the most stable and durable of the Hyperwarp trio, geared for longer marathons at slower paces — your pace, essentially. At 85 kg, that extra cushioning and durability matter; you'll compress the foam more than lighter runners, so the thick midsole is a real advantage. The key: log your training miles in it now. You want 50–100 miles in the shoe before race day so your legs know how it responds when fatigued. A pure racer would feel alien at mile 18. One follow-up: how many weeks out is your marathon, and how much weekly mileage are you running right now? That'll help me confirm the Hyperwarp Pro is durable enough for your build-up.

assistant: You're absolutely right, and I apologize — I wasn't listening carefully enough. The Mizuno Hyperwarp Pure is a pure racer with a carbon plate, which is exactly the wrong shoe for your situation. At 4:30 pace, you need a long-run or daily trainer built for durability and comfort, not speed. Carbon plates are wasted on slower paces and add stiffness you don't need. Looking at what I have in my data right now, I'm hitting a real gap: the retrieval brought back only the Hyperwarp Pure (a racer), and my wiki context shows two shoes flagged as "best for heavy runners" — the **New Balance FuelCell Rebel v4** and **Puma MagMax Nitro 2** — but I don't have their full cards with specs and details to give you a proper recommendation. Here's what I need to do this right: can you tell me your weekly mileage right now and how many weeks until race day? That'll help me understand your training volume and whether I should be looking at a daily trainer (300–500 mi life) or a long-run specialist. Once I know that, I can either pull the full details on those heavy-runner shoes or ask my data team to surface a proper long-run or cushioned daily trainer that matches your weight and pace target. I want to get you into the right shoe, not push you toward speed gear you don't need.
