Within each brand there are wide and narrow lines. At Nike, Phantom 6 and Tiempo are wide and the Mercurial is narrow. At adidas, Copa Pure and Mundial are wide, Predator is medium and F50 is narrow. Compare the line, not the brand.
Calfskin leather that gives, a deep lacing system and a separate tongue that opens far. This makes it strong for a high instep.
The widest Nike last, with extra height in the toe box and a roomy heel. The knit upper stretches.
For the question of Nike vs adidas soccer cleats fit, the line matters more than the brand, because each brand has wide and narrow lines. At Nike, the Phantom 6 and the Tiempo are wider than the Mercurial. At adidas, the Copa Pure and the Copa Mundial are wider than the Predator and the F50. So which brand runs wider depends on the line: the widest Nike (Phantom 6) and the widest adidas (Copa Pure IV or Copa Mundial) are closer to each other than the widest and narrowest lines within a single brand.
Below you will read which lines run wide for each brand, how sizing works and where sources contradict each other. The cards at the top of this page show the two models we compare most directly. Our judgments rest on manufacturer information and independent fit tests.
Neither brand has a separate wide line. Both have lines with a roomier last. Nike itself describes the Mercurial as snug and points wide feet to the Tiempo or Phantom.
At adidas the Copa models are the widest, followed by the Predator. The F50 is narrow. If you want to place a wide foot in a brand, look at the line first and the brand second.
The table sets the main lines side by side, with the zones where pressure shows up.
| Model | Forefoot | Instep | Heel | Material | Sizing | For whom |
|---|---|---|---|---|---|---|
| Nike Phantom 6 | Extra toe height and forefoot width, wider than any Mercurial | High volume, knit tongue with stretch | Broad midfoot and roomy heel | Flyknit or Gripknit, no break-in | About a quarter size long | Wide feet, high instep, kids with wide feet |
| Nike Tiempo Maestro | Low, pointed toe box | Low volume | Wide, round heel | TechLeather, does not stretch | True to size, do not go down | Wide midfoot and heel |
| Nike Mercurial Vapor and Superfly | Narrow last, low pointed toe box | Low volume | Closes tight around the foot | Atomknit, almost no stretch | Snug, half a size up for more room | Narrow to standard feet |
| adidas Copa Pure IV | Roomy forefoot, high toe box | Separate tongue, deep lacing | Strong heel lock, a narrow heel can slip | Calfskin, stretches | Elite true to size | Wide forefoot, high instep |
| adidas Predator | Medium-wide forefoot, high toe box | Moderate, FT version roomier | External heel counter, a narrow heel slips | Textile mesh, 30 to 45 minutes of break-in | True to size | Medium to moderately wide feet |
| adidas F50 Hyperfast | Narrow to standard | Low volume | A narrow heel fits | Thin speed synthetics, no stretch | True to size | Narrow to standard feet |
The Nike Phantom 6 is the widest Nike, with extra toe height and a broad midfoot and heel. It has high volume and suits a high instep. Know that the heel on the Low is especially roomy, which lets a narrow heel slip.
The Tiempo Maestro is wide in the midfoot and heel, with a low toe box. The Mercurial Vapor and Superfly are the narrowest Nikes, also in youth sizes. We advise against them for wide feet. For more, see Nike soccer cleats for wide feet.
The adidas Copa Pure IV has a roomy forefoot but a shaped midfoot. The Copa Mundial has a classic wider last. The Predator has a medium-wide forefoot with a high toe box, but a shaped midfoot, and it needs break-in time.
The F50 Hyperfast is narrow to standard with low instep volume and is not meant for wide or flat feet. The F50 EVO and the Messi Elite are the milder variants. For more, see adidas soccer cleats for wide feet.
Nike writes on product pages for models such as the Tiempo Legend 10 Academy and the Vapor 17 Elite that the cleat fits snug and that you can order half a size up for a roomier fit. The Phantom 6 runs about a quarter size long. The Tiempo Maestro is true to size and you do not go down. If you are unsure about size, read how Nike soccer cleats fit.
At adidas the Copa Pure IV Elite is true to size, and half a size down gives a glove fit after break-in. The Copa Mundial runs long and goes half to a full size down. The Predator is true to size. adidas uses third sizes such as 46 2/3 and 47 1/3, which gives more choice than at Nike.
If you go half a size up for a roomier fit, that makes the cleat longer and not wider. So do not go up a size for width. Our size converter helps with US sizing across brands.
On the adidas Predator, sources differ. Some call it suitable for wide and narrow feet, others call the 2026 version narrower than the previous one with a shaped midfoot. We follow the more extensive independent review and rate it medium to moderately wide, with a caveat for a wide midfoot.
For the adidas F50 Elite, one review says it is not for wide feet, while another source calls the midfoot surprisingly roomy. We follow the more extensive review and call the F50 narrow to standard.
At Nike, the Phantom 6 is the pick for wide kids’ feet: the junior sizes run consistently wider according to sources. The Mercurial junior is the narrowest Nike. At adidas there are youth versions of the Copa Pure (League and Club), the Predator (League and Club) and the F50, with the Copa Pure fitting a wide foot best. For sizing, read how adidas soccer cleats fit.
