Claude vs ChatGPT: Running shoes for overpronators training for a half marathon. Join the debate.: Brooks Adrenaline GTS

For a 42-year-old overpronator building up to a first half marathon, the ASICS Gel-Kayano 31 is the strongest starting point — it's a stability shoe with enough cushioning to protect joints over longer training runs, and it's forgiving enough for someone whose mileage is ramping up. The structured support addresses the overpronation without being aggressive. If budget is a factor, the Brooks Adrenaline GTS 24 is a genuine rival — slightly less cushioned but excellent stability and often easier to find on sale. My lead recommendation is the ASICS Gel-Kayano 31. It earns its price over the course of a half marathon training block.

Fair challenge. For a first half marathon, fatigue in miles 10-13 is exactly where cushioning pays off — and the Gel-Kayano 31's FlyteFoam Blast+ midsole does hold up better under accumulated load than the Adrenaline's DNA Loft v3. But you're right that the Adrenaline's responsiveness keeps turnover fresher, which matters late in a race too. It's not a clear win either way. The deciding factor for a 42-year-old overpronator on their first half is training volume, not race day. Months of long runs demand cushioning durability more than race-day snap. The Kayano absorbs that cumulative load better. I'm holding the Gel-Kayano 31 as the lead recommendation, but the Adrenaline GTS 24 is the right call if they're lighter or prefer a more natural feel.

Good point — the lower drop does shift more load to the forefoot over distance, which matters at 25 miles per week across a long training block. That actually strengthens the case for the Brooks Adrenaline GTS 24. The 12mm drop reduces forefoot demand at higher mileage, the DNA Loft v3 cushioning is more than adequate for a first half marathon training load, and the GuideRails stability system handles overpronation without over-correcting. Final recommendation: Brooks Adrenaline GTS 24. For a 42-year-old overpronator running 25 miles per week toward a first half marathon, the higher drop reduces forefoot fatigue accumulation over long runs, the stability is reliable, and it's a shoe that will carry them comfortably through the training block and across the finish line.
