assistant: Breaking 3 hours is a serious goal — you're looking at sub-6:52/mile pace, so you need a shoe that rewards speed without sacrificing the comfort and stability you'll need to hold that pace for 26.2 miles. Before I narrow it down, I need to know a couple of things: 1. **What's your current weekly mileage, and how many miles are you typically logging in your long runs?** (This tells me how much cushioning and durability you need.) 2. **Do you tend to be a heel striker, midfoot striker, or forefoot striker?** (Some of these shoes are more forgiving on the heel; others reward forefoot engagement.) 3. **Any history of injuries, or do you have a preferred cushioning feel** — do you like a firmer, more responsive shoe, or something softer and bouncier? These details will help me point you toward the right super shoe for your 3-hour attempt rather than just listing all the fast options.

assistant: Great — forefoot striker chasing sub-3 is aggressive but totally doable with the right shoe. Your footstrike and weight are key here: you need a shoe that rewards forefoot engagement without sacrificing the stability and durability a heavier runner needs over 26.2 miles. **My top pick: Saucony Endorphin Elite v2** This is the best balance of softness, energy return, and marathon-distance forgiveness for a heavier forefoot striker. The incrediRUN foam is exceptionally soft and bouncy — EDDBUD measured it at Shore A11, which is genuinely plush — and the forked carbon plate sits forward to give you strong propulsion off the toes. Doctors of Running notes it delivers "max cushion without max weight," and EDDBUD specifically flagged it as ideal for heavier runners wanting impact protection. At 201g, it's not ultralight, but the softness and energy return make it feel faster than the weight suggests. One caveat: the soft midsole lacks stability, so you'll need clean form to hold pace late; if your form tends to break down, the Endorphin Pro v5 (below) is the safer pick. **Alternative if you want more stability: Saucony Endorphin Pro v5** Heavier, firmer, and more stable than the Elite v2. EDDBUD calls it "the best option for heavier runners" with a wide landing platform and resilient foam that holds up through 100+ miles. The trade-off is less pop and a slightly slower feel, but the consistency and durability are excellent for a marathon grind. **Speed-focused alternative: ASICS Metaspeed Sky Tokyo** If you're confident in your form and want the lightest, poppiest shoe here, this is it — 159g with FF Leap foam that's wildly bouncy. Kofuzi ran it through 100 miles with consistent ride quality. The catch: it's narrow in the heel and demands good form retention. Forefoot strikers love it, but heavier runners should size carefully and test the fit. <details> <summary><strong>What reviewers say</strong></summary> **Saucony Endorphin Elite v2:** - EDDBUD (9.0/10): "Wildly soft, forgiving max-cushion racer with standout impact protection and surprising durability — a top-five shoe of the year, especially at discount... extremely soft and compressive Incred foam with unmatched impact protection; lowers heart rate ~5-6 bpm at steady pace. Legs feel great the next day." - The Run Testers (8.5/10): "Exceptionally soft and springy carbon racer... makes other shoes feel lifeless... delivers huge energy return." **Saucony Endorphin Pro v5:** - EDDBUD (8.5/10): "Wider, more stable and durable super-shoe with a smooth, consistent ride that suits heavier runners... Wide landing platform in the heel that protrudes from the back of the shoe like a ski." - FORDY RUNS (9.0/10): "Forgiving, stable carbon-plated racer that performs under pressure and stands out as the go-to stability super-shoe for 2026... stable and controlled with speed roll geometry aiding heel-to-toe transition." **ASICS Metaspeed Sky Tokyo:** - Kofuzi (9.0/10): "Excellent marathon racer that combines cushion and speed effectively, holding up well through 100 miles with consistent ride quality and plenty of life remaining." - The Run Testers (9.0/10): "Light, responsive, and poppy carbon plate shoe... Very fast transition onto the forefoot with notable pop off the toes." </details> One more quick question: **Are you currently logging 50+ miles per week in training?** That'll help me confirm the Endorphin Elite v2 is durable enough for your build, or if you'd benefit from the Pro v5's extra resilience.

assistant: Good catch — you're right to push back. Looking at the retrieved data, **only the Saucony Endorphin Pro v5 is explicitly flagged as suitable for heavier runners**. EDDBUD specifically notes it has "a wide landing platform in the heel that protrudes from the back of the shoe like a ski" and calls it "the best option for heavier runners" with resilient foam that holds up through 100+ miles. The **Saucony Endorphin Elite v2** is my original top pick, and while EDDBUD does mention it's good for "heavier runners wanting max cushion without max weight," the shoe is fundamentally soft and unstable — which means it demands clean form retention. At your weight, late-race form breakdown becomes a real risk, and that softness could work against you over 26.2 miles. The **Mizuno Hyperwarp Elite** is another solid option here. EDDBUD rates it 9.0/10 and specifically praises its stability and predictability — "rewards faster cadences; versatile across paces." At 170g it's light, but the dual-layer PEBA/TPE midsole is more resilient than the Elite v2's supercritical foam, and reviewers note it "locks into half-marathon and marathon pace well." **My revised recommendation for you as a heavier forefoot striker:** 1. **Saucony Endorphin Pro v5** — the safest, most durable pick with explicit heavy-runner support 2. **Mizuno Hyperwarp Elite** — lighter and more responsive than the Pro v5, but with better stability than the Elite v2 3. **Saucony Endorphin Elite v2** — only if you're confident your form holds strong through mile 20+ The trade-off: Pro v5 is heavier (215g) and less poppy than the Elite v2, but it'll be more forgiving when you fatigue. Hyperwarp Elite splits the difference — lighter than the Pro v5 but more stable than the Elite v2. **Does that shift your thinking, or are you set on chasing the maximum softness/pop of the Elite v2 despite the stability risk?**
