adidas Evo SL vs Adios Pro 4: Do You Need Carbon for a 10K?

Do you need carbon for a 10K?

No. For most runners on a 10K plan, the Evo SL is the better buy. You race once at the end of an 8-week plan like Hal Higdon's Novice 10K, and the other 23 runs are the ones that make you faster. A shoe you can do those runs in is worth more than a shoe you wear once. Even RunRepeat's own Adios Pro 4 review says that for runners who find the cost or stiffness of traditional super shoes off-putting, "the adidas Adizero EVO SL is a smarter choice."

That doesn't make carbon pointless at 10K pace. Plated super shoes lower the energy cost of running, and a 2026 ETH Zurich study found the effect held for moderately trained runners at 7.5 to 12 km/h (about 12:52 to 8:03 per mile), not just for the elite athletes in the original 2018 study. Neither study tested the Adios Pro 4 itself, and the 2026 study found comfort mattered more than economy to which shoe runners preferred. So the honest answer is: carbon can help, but at this level it's a finishing touch, not a requirement. Our deeper read on the research is in are carbon-plated shoes worth it?

Specs side by side

Each value links to its source. The Adios Pro 4 row shows both the maker's claimed stack and RunRepeat's lab measurement, which came in lower. No width options are listed on our source for the Adios Pro 4.

On paper they're close: both around 7 to 8 oz, both built on Lightstrike Pro, similar drops. The difference is in the midsole's backbone and the job each shoe is built for. The Adios Pro 4 has Energy Rods 2.0, five carbon-infused rods that RunRepeat says mimic the bones of the foot, and a taller claimed heel of 39 mm. The Evo SL has no plate or rods at all.

Level by level: which to buy

If you're still at the run/walk stage, both shoes are the wrong starting point; our best running shoes for beginners are built for that job. At the 10K level, the Evo SL does everything a novice plan asks, including race day. Once you move to the half, the two start to work as a pair: Believe in the Run lists daily training, long runs and uptempo as the Evo SL's best uses, and the Adios Pro 4 becomes the race-day shoe. For marathon long runs, note that the Evo SL's 32 mm forefoot is less stack than the max-cushion super trainers built for 18 to 20 mile runs.

The differences that matter

Plate or no plate

Believe in the Run's reviewers found the Evo SL "soft but bouncy" and suitable for "double-digit miles," and position it for training rather than as a race-day shoe. RunRepeat takes it further, recommending it to beginners who want one shoe to train and race in and calling it "undoubtedly capable of handling a full marathon with ease." The Adios Pro 4 is the opposite brief: a race shoe first. RunRepeat's 5K and 10K guide gives it its "best energy return" award, and its review calls it "versatile from 5K to marathon distances."

How you land

This is the deciding factor for many runners. RunRepeat describes the Adios Pro 4 as really unstable for heel strikers because of its narrow heel, and points heel strikers who need support to Saucony's Endorphin Pro line instead. The Evo SL doesn't solve that problem: RunRepeat's Evo SL review describes a "distinctly narrow" heel for its stack height, says it "isn't a stability shoe, making it only suited for neutral runners," and suggests pronounced heel strikers also look at shoes like the ASICS Novablast and HOKA Mach. If you're a neutral runner who lands midfoot or only lightly on the heel, either shoe works; if you land hard on your heels, look past both.

Weight

The race shoe is lighter despite the taller heel: 7.1 oz men's claimed for the Adios Pro 4 (6.4 oz women's) against 7.9 oz for a men's 9 in the Evo SL. Both are light by trainer standards; the Adios Pro 4 simply spends every gram on race day, while the Evo SL keeps enough durability in the build to be run in every week.

Rods, a plate, or nothing

adidas uses three different approaches across these shoes. The Adios Pro 4 has Energy Rods 2.0, five carbon-infused rods rather than a single full-width plate. The Boston 13 uses carbon-based Energy Rods 2.0 "instead of a carbon plate," and RunRepeat's lab found them less rigid than full carbon plates. The Evo SL has nothing at all: its speed comes from the full-length Lightstrike Pro midsole. If you've never run in a plated or rodded shoe, that's one more reason the Evo SL is the gentler introduction.

Fit

RunRepeat reports the Adios Pro 4 fits slightly small, with a narrow, tapered toebox that suits narrower feet. Believe in the Run found the Evo SL true to size and, for one reviewer, roomier than he wanted for fast work. RunRepeat lists the Evo SL in normal and wide widths. Both reviews flag the Evo SL's non-gusseted tongue.

How long they last

Race foams trade durability for rebound. RunRepeat's Adios Pro 4 review says these materials have a "golden" window of about 100 miles, after which performance declines rapidly. That's fine for a race-and-key-workouts shoe; it's a poor fit for a shoe you'd run in three times a week. The Evo SL is built for exactly that weekly use.

Using both: train in one, race in the other

If you end up owning both, the split is simple. The Evo SL does the training: the easy runs and, once you're on a plan like Higdon's Intermediate 10K, the 400-meter intervals at 5K race pace and the tempo runs, which Higdon describes as "a continuous run with a buildup in the middle to near race pace." The Adios Pro 4 is saved for races, plus one or two key sessions before a race to make sure it fits and feels right at speed.

Two practical notes. RunRepeat says the Adios Pro 4 fits slightly small, so try it on (with your race socks) rather than ordering your Evo SL size blind. And given RunRepeat's "golden" window of about 100 miles, keeping it for races is what makes it last through a season of 5Ks and 10Ks.

Two alternatives worth a look

adidas Adizero Boston 13. The middle ground between these two: carbon-based EnergyRods like the Adios Pro, but in a firmer, heavier trainer (9 oz for a men's 9). The Believe in the Run review lists daily training, tempo and race day as its best uses, and says the Adios Pro 4 would still be the pick for race day. It suits a runner who wants some rod-driven snap in a shoe they can train in.

Saucony Endorphin Pro 5. If you've decided you want carbon but you're a heel striker, this is the super shoe to look at. RunRepeat calls it "the best super shoe for beginners or runners who feel uncomfortable with unstable designs," and names it the best 5K and 10K shoe for heel strikers.

Who should buy which

• First 10K, or racing once or twice a year: Evo SL. Train in it, race in it.
• Pronounced heel striker: neither. For carbon, the Endorphin Pro 5; for a plateless trainer, our 5K and 10K trainer picks include wider-based options.
• Racing a 5K or 10K most months, chasing times: Adios Pro 4, kept for races and key sessions, with a trainer alongside it.
• Moving up to the half or marathon: both. The Evo SL as the trainer, the Adios Pro 4 as the race shoe. See our best half marathon race shoes for other race-day options.
