Most reviews of the Adidas Adios Pro 4 will tell you it is the best marathon shoe of the year. The honest answer is more specific. The Pro 4 is a high-performance carbon-plate racer that suits a particular kind of runner and punishes the rest. Whether you are that runner is a question marketing copy will not answer for you. This review will.
The Adios Pro 4 problem in Indian running
Indian runners have been sold a story: buy the latest carbon shoe, run faster, win the chase. The story works for Adidas. It works for Nike. It works for every brand selling super-shoes in this country. It does not work for you unless your training has caught up to your gear.
The Pro 4 is a tool. Tools are useful when applied to a fitting job. They are useless or harmful when applied to the wrong job. The wrong job, in this case, is a runner asking a carbon-plate marathon shoe to compensate for an undercooked training block.
What the carbon plate actually does
The plate is not magic. It is a stiff lever that, combined with high-rebound foam, recycles a measurable percentage of the energy you put into each stride. The percentage scales with cadence, ground contact time, and pace. Elite runners with fast cadence and short ground contact extract maximum benefit. Recreational runners with longer ground contact and slower cadence extract less.
That is not opinion. That is biomechanics. The Pro 4's plate geometry is optimised for the elite runner profile. If your marathon pace is 6 min per km, the shoe still helps, but the gap between your time in this shoe and your time in a quality non-plated racer narrows to a handful of seconds per km.
The runners the Pro 4 was actually designed for
I will name the runner profile that gets maximum value from the Pro 4. Indian runners targeting sub-3:00 marathon times. Indian half-marathon racers chasing sub-1:25. National-level competitive masters runners. That is the list of runners where the Pro 4 delivers a meaningful advantage that justifies the cost and the durability trade-off.
If you are running a 3:30 to 4:00 marathon, the Pro 4 still works for you. It is faster than a normal trainer. But the advantage shrinks, and so does the value proposition. At slower paces, the Adios Pro 3 at clearance pricing or a tier-down carbon shoe gives you most of the benefit at half the cost.
The 4:00-plus marathon argument
For runners running 4:00 plus marathons, the Pro 4 is not the answer. The biomechanical advantage is small at those paces, the foam compression rate is faster than you think because total time on feet is longer, and the cost per usable kilometre balloons. Build the engine first. Pick a more durable cushioned daily trainer for the bulk of your training, save the carbon for race day, and use a less expensive plated shoe if you must have one.

What changed from the Pro 3 to the Pro 4
Adidas refined the geometry, not revolutionised it. The midsole gets a slight tweak, the upper gets lighter, and the heel collar redesign sits flatter against the Achilles for less rubbing on longer runs. Anyone telling you the Pro 4 is a step-change over the Pro 3 is selling you the shoe. The honest answer is that it is an iteration, not a revolution.
That matters for your buying decision. If you already own the Pro 3, do not upgrade unless the Pro 3 is at end-of-life. The marginal gain is not worth the spend. If you are buying carbon for the first time, the Pro 4 is the better long-term pick because it is the current generation and will hold resale value longer. Our gear archive tracks every super-shoe release for cross-referencing.
The race-day-only argument
Some reviewers say to use the Pro 4 in training too. They are wrong. Carbon-plate super-shoes have a finite lifespan measured in race-pace kilometres. Burning those kilometres on Tuesday tempo runs steals them from race day.
Reserve the Pro 4 for two uses. Race day, and one race-pace simulation run two to three weeks before your goal race. Everything else goes in your daily trainer or your plated tempo shoe. Do not let an Instagram reviewer convince you otherwise. Their kilometres are not your kilometres.
The Indian race calendar lens
Most Indian marathons run from October to February. That is your race window. Buy the Pro 4 in August or September, do one shakeout, race in October or November, save the shoe for one more major race in December to February. That is two to three races in a year on a single pair of shoes.
That is the lifecycle of a super-shoe. Anyone telling you to use it across an 18-week training block is shortening that lifecycle and forcing you to buy again next October. The brands are happy with that math. Your wallet should not be.
Storage matters in Indian humidity
PEBA-based foams degrade with heat and humidity. After your race, clean the shoe of mud and salt, dry it fully, and store it in its box in a cool cupboard. Direct sunlight kills super-shoe foam faster than mileage does. Indian coastal cities — Mumbai, Chennai, Kolkata, Goa — make this a real concern in summer months.
How to spend smarter than the brand wants you to
Here is a different way to think about your gear spend. Take the price of a Pro 4. Divide it by the number of races you will run in it. That is your cost per race. For most Indian recreational runners, the answer is uncomfortable.
Now take a cheaper plated trainer plus a quality daily trainer. Total spend is often similar, but you cover more of your weekly training with better tools. You race in the plated trainer if you are not at sub-3:00 marathon pace, and your finish time changes by seconds, not minutes.
The Pro 4 is a brilliant shoe. It is also a luxury good for the Indian recreational runner. Both can be true. The conversation should be about which runners benefit from the brilliance and which runners are buying the luxury. Most reviews refuse to separate the two. I just did.
