Structure 25

Yes, for most runners it fits true to size, so order your usual Nike length. The midfoot is standard-to-snug and the heel lockdown is secure, which suits a supportive trainer that wants to hold your foot centred. The toe box is adequate rather than roomy, so if you have wider feet or like extra wiggle room, look for a wide fitting or consider going half a size up. We would not size up on length alone for most runners.

Yes, that is exactly what it is built for. The Structure 25 is a stability shoe aimed at mild to moderate overpronators, and it provides support through a wide, firm platform and a secure upper rather than an aggressive medial post. That means the correction feels natural rather than forced. If you have severe overpronation and need serious motion control, you may want something more specialised, but for the majority of runners wanting a little guidance, it is well judged.

You can, and its stability actually helps as your form tires late in a race, but it is not a fast marathon shoe. At 289g it is heavy, and the firm, planted ride prioritises support and durability over speed and pop. Think of it as a solid choice for training miles and for slower, support-focused marathon runners rather than anyone chasing a personal best. If you want a quicker race-day feel, look to a lighter tempo or carbon shoe instead.

It can be a sensible beginner shoe, especially if you overpronate or simply want a stable, forgiving-to-run-in trainer that will not fall apart quickly. The support and durability suit new runners building mileage, and the firm platform gives a planted, confidence-inspiring feel. The main caveats are the weight and the firm cushioning, which some beginners find less comfortable than a softer trainer. If you want plush and soft over structured and supportive, a neutral cushioned shoe may suit you better.

Both are traditional stability daily trainers built for mild overpronators, so they compete directly. The Structure 25 leans firm and planted with a durable, no-nonsense feel, while the Adrenaline GTS 25 tends to offer slightly smoother, more cushioned guidance through its support system. Neither is light, and both are workhorses rather than speed shoes. It often comes down to fit and price, so check the current price on both and pick the one that suits your foot shape best.

Durability is one of its strengths. The firm midsole and hard-wearing upper are built to survive high weekly mileage, and the ride holds its shape long after softer, bouncier trainers have packed out. As a rough guide, expect a well-built daily trainer like this to give you a good stretch of consistent training miles before the cushioning noticeably softens, with the outsole rubber typically outlasting the foam. It is a shoe you buy to rack up miles, not to baby.
