assistant: For overpronation at 30 mi/wk, you want a modern stability shoe with guide rails or a medial post—something that controls inward roll without feeling clunky. The **Brooks Glycerin GTS v22** is your best match: it's a true stability trainer with a medial post and lateral guide rails that Doctors of Running calls "one of the few current shoes retaining a medial post" and notes delivers "high stability with distinct arch pressure." It's well-cushioned (39/29mm stack, 10mm drop), fits true to size, and handles daily training miles comfortably. The DNA Tuned midsole is firmer than older versions, which helps with control. If you want a lighter daily trainer that still offers stability support, the **Saucony Guide v18** is a solid alternative—it's a proven stability shoe at the same $140 price point as the Adidas, with high cushioning for the daily grind. One quick question: do you have a preference between a shoe with a visible medial post (like the Glycerin) versus one with guide rails that feel more neutral-leaning? That'll help me confirm the Glycerin is the right call.

assistant: The **Brooks Adrenaline GTS v25** is still a solid stability trainer, but the **Brooks Glycerin GTS v22** has genuinely dethroned it as the premium stability choice—and it's a meaningful upgrade for overpronation at 30 mi/wk. Here's why: The Adrenaline v25 uses DNA LOFT v3, which is softer and plushier but less controlled. The Glycerin v22 swapped in the firmer DNA Tuned midsole and brought back a true medial post with lateral guide rails. Doctors of Running calls the Glycerin v22 "one of the few current shoes retaining a medial post" and notes it "delivers high stability with distinct arch pressure"—that's the real control you need for overpronation. The Glycerin v22 also has a wider forefoot fit, which pairs better with overpronation biomechanics. The Adrenaline v25 has "mixed reception" partly because it softened the stability feel compared to earlier versions; reviewers wanted more defined support. The Glycerin v22 corrected that. Both are 10mm drop, true to size, and priced similarly ($165 vs $155), but the Glycerin v22 is the stronger stability platform right now. That said, if you've been running in the Adrenaline v25 and it's working for you, there's no urgent reason to switch—fit familiarity and a shoe that's not broken are real assets. What's prompting the question: are you wearing yours out, or looking to rotate in a second shoe?
