assistant: You're in the sweet spot for a cushioned daily trainer that can handle both your easy miles and the volume ramp-up ahead. At 85 kg with a heel-strike pattern and a 4:30 target, you don't need a racing flat yet — you need a shoe that protects your legs through 16–20 weeks of build-up, then we can talk race day. Before I narrow it down: **Do you have any history of injuries or biomechanical concerns** (knee pain, shin splints, calf tightness, plantar fasciitis)? And **are you currently running in a shoe you like**, or starting fresh? That'll help me pick between cushioned daily trainers vs. something with a bit more support. In the meantime, here are three strong options for marathon build-up: **Nike Vomero Premium** — maximal cushioning (54/44 mm stack) with a 10 mm drop that suits heel strikers. Built for recovery and long runs; the ZoomX PEBA foam is soft underfoot but responsive enough for easy-paced miles. At 329g it's heavier, but that's the trade-off for protection on high-mileage weeks. Well-regarded for exactly this phase of training. **Brooks Glycerin GTS v22** — high cushioning with mild stability and a 10 mm drop. Doctors of Running notes it's firmer and more secure than the previous version, with a noticeable heel bounce once broken in. If you've had any hint of overpronation or just want a touch of medial support as volume climbs, this is a solid choice. True to size, wide forefoot. **ASICS Megablast v1** — maximal cushioning (no plate) with excellent expert reception. Lighter than the Vomero at a similar stack height, so it's a good middle ground if you want protection without the weight penalty. Well-suited for the long-run phase of marathon training. Once you answer about injury history, I can refine which of these three is the best fit for your body.

assistant: Perfect — you're thinking like a smart marathoner. Build-up is where injuries happen, and the right daily trainer makes all the difference. Since you're a heel striker at 85 kg ramping volume, I'm focusing on cushioned trainers that'll protect you through 16+ weeks without wearing out your legs. **Nike Vomero Premium** — your top pick here. Maximal cushioning (54/44 mm stack) with a 10 mm drop that matches your heel-strike pattern perfectly. ZoomX PEBA foam is soft on impact but responsive enough for easy-paced miles; you won't feel sluggish on recovery days. At 329g it's heavier, but that weight buys you protection on high-mileage weeks. Well-regarded for exactly this phase — long runs, easy miles, the grind of marathon build-up. **ASICS Glideride Max v2** — lighter alternative (261g) with the same maximal cushioning but a lower 6 mm drop. If the Vomero feels too heavy or you want less heel-to-toe pitch, this is excellent. FF Blast Max foam is responsive without sacrificing protection. The trade-off: that 6 mm drop is gentler on the calf, but heel strikers sometimes prefer the higher drop of the Vomero. Both are well-regarded; this one just gives you a different ride character. **Brooks Glycerin GTS v22** — if you want mild stability built in (useful as fatigue creeps in during peak mileage weeks), this delivers. Doctors of Running notes the v22 is firmer and bouncier than the previous version, with noticeable medial support and a 10 mm drop. At 303g and $165, it's also the most affordable option here. The caveat: it's a stability shoe, so it's best if you have any hint of overpronation or just prefer that locked-in feel under load. I'm dropping **ASICS Megablast v1** from my earlier suggestion — it's excellent (expert reception is outstanding), but it's a speed-training shoe with a lighter build, not ideal for the high-mileage, injury-prevention focus you need right now. Save it for tempo work once you're deeper into build-up. **Quick question:** Do you tend toward neutral landings or do your feet roll inward a bit under fatigue? That'll help me confirm whether the Glycerin GTS's stability is overkill or a genuine asset for you.
