Most articles will tell you the Adidas Adios Pro 4 is a race-day shoe and that you should not train in it. That is lazy advice. The honest answer is that a carbon race shoe has three legitimate training use cases — and if you ignore them, you waste both the shoe and the workout.
The lazy convention I am rejecting
The standard playbook for carbon-plated race shoes goes like this: keep them in the box until race day, accumulate three to five sessions of "familiarisation," and otherwise treat them as untouchable. This advice exists because somebody once read that carbon plates last only X kilometres, panicked, and the rest of the running internet copy-pasted the panic.
I am calling that bad advice. Here is why. The Adios Pro 4 has a finite life, yes. But foam degrades through compression cycles, not through calendar time. A shoe kept in a box still ages — the foam slowly relaxes, the adhesives age, the upper materials oxidise. You are not preserving anything by hoarding. You are just paying ₹20,000+ for a shoe you barely use.
Use the shoe. Use it well. Train with intent.
Use case 1: The breakthrough threshold session
Why this works
Threshold sessions — the 4 x 2 km, 5 x 1.6 km, 20 x 400 m varieties — are where you stack the work that determines half-marathon and marathon outcomes. The Adios Pro 4 makes these sessions slightly easier at a given heart rate, and slightly faster at a given perceived effort. You are not cheating. You are training your nervous system to operate at race-day pace in race-day conditions.
The honest counter-argument
Some coaches will tell you that training in a softer trainer builds leg strength and that the race shoe is a "finishing" tool. There is a kernel of truth in this for elites who already have years of base. For everyone else — the working-age Indian runner squeezing 35-45 km a week between job, family, and Bangalore traffic — you do not have time to train in two different feels. Pick one race shoe. Use it for the workouts that resemble the race.
Use case 2: The race-pace marathon long run
The session
Six to eight weeks out from your marathon, you should run at least one long session at marathon pace. Most plans call for 25-30 km with the final 10-15 km at race pace. This is exactly the session for which the Adios Pro 4 was built. Wear the shoe you will race in, on a surface similar to your race surface, at the pace you intend to hold.
The pushback
"But the carbon plate will mask weaknesses you should be training out." Wrong framing. The plate does not mask weaknesses — it amplifies the ones you already have. If your form breaks down at 30 km in trainers, it breaks down faster and harder in carbon. The race-pace long run is exactly when you should discover this, six weeks out, with time to do something about it.
Indian context
Run your marathon-pace long run in race-similar conditions. If your marathon is the Tata Mumbai Marathon in January, that means flat road and humid air. Train accordingly. If it is the ADHM, that means cool early-morning Delhi air. Train accordingly. Match conditions, not just distance.
Use case 3: The race-week tune-up
The session
Three to five days before race day, run a short tune-up — 4-6 km easy plus 4-6 x 100 m strides — in the race shoe. The objective is not training adaptation. The objective is to confirm that the shoe still fits, that nothing is fraying, that the foam still feels lively, and that your nervous system remembers what race pace feels like.
Why this matters more in India
Indian race-day weather is often a wildcard. The race-week tune-up gives you one final read on whether the shoe pairs well with the temperature and humidity you are about to encounter. If you raced your last half in cool Bangalore October air and your marathon is in humid Mumbai January, your foot may swell differently. The tune-up catches that.
What I am not telling you to do
Do not use the Adios Pro 4 as your daily trainer
This is the line. Carbon shoes are expensive, the foam degrades faster than EVA, and the geometry is aggressive — the Adios Pro 4 is not built for the slow shuffle that should comprise 70-80% of your weekly mileage. Save the carbon for the sessions where the carbon earns its money. Compare cheaper plated alternatives for everyday tempo work in the cheaper super-shoes guide.
Do not use it for recovery runs
Recovery runs are about easy pace and low impact. A carbon shoe at recovery pace is just an expensive way to make your easy runs feel weird. Use a daily trainer. The Adios Pro 4's job is to make your hard sessions count.
Do not train in it if you have not done the base
If you are running fewer than 30 km a week, the Adios Pro 4 is overkill. The plate will fight your form, the foam will overwhelm your stabilisers, and you will get injured. Build base in a daily trainer first. Look at the options in the STRIDD gear hub for ₹8,000-12,000 daily trainers that fit a base-building phase.
The four-shoe rotation that earns the carbon
If you are committing ₹20,000+ to a carbon race shoe, you should also commit to a rotation that keeps it alive for race day. The shape I recommend:
- Easy / long runs: Max-cushion daily trainer. Browse options at the Running Lab home.
- Steady runs and recovery: Lightweight daily trainer.
- Threshold and race-pace sessions: Adios Pro 4.
- Race day: Adios Pro 4 (the same shoe, used disciplined).
To structure the week around these shoes, run your inputs through the STRIDD plan generator.
The race-shoe market is a fight worth picking
Most Indian running content treats carbon shoes as untouchable artifacts. Some content treats them as miracle gear. Both positions miss the point. A carbon race shoe is a tool. It has three good training use cases. Used inside them, the shoe earns its ₹20,000+. Used outside them, you are spending money on a fashion accessory. Want the broader carbon landscape?

Next step
Build the training block that the Adios Pro 4 is supposed to serve. Train hard, train smart, race once. The shoe will return what you put into it.
