Do ASICS Have a Wide Toe Box? 27 ASICS Measured
A lab measured 27 current ASICS at the big toe. Most new versions got narrower. A podiatrist on which ASICS suit wide feet and bunions.

Not really. ASICS sits just under average at the toes, and most of its newest shoes are narrower there than the versions they replaced. A lab has measured 27 current ASICS running shoes at the big toe. The roomiest is the Noosa Tri 16 at 77.3 mm; the average road shoe measures 73.2 mm; and the ASICS most of my patients wear, the Gel-Kayano 33, Gel-Nimbus 28, GT-2000 15 and Novablast 6, all measure below that. What ASICS does well is widths: a Wide or Extra Wide of most of its everyday trainers.
This is a measurement page, and we did not take the measurements. Every toe box figure here comes from RunRepeat’s lab, which fills each shoe with a setting gel and measures the mould, read from its published reviews on 16 October 2026. ASICS publishes none of these numbers. The widths ASICS sells are from asics.com, read the same day. There is no Podiatrist Tested score or seal on this page; the interpretation and clinical advice are mine. How we test.
The short answer
- Are ASICS wide at the toes? About average. Of the 27 current ASICS a lab has measured, 8 beat the average for their category at the big toe and 19 fall short.
- The roomiest: the Noosa Tri 16 (77.3 mm) and, for trail, the Trabuco 14 (76.3 mm). The roomiest everyday trainer is the Gel-Cumulus 28 at 74.4 mm, and it comes in Wide and Extra Wide.
- Newer is narrower: 15 of the 21 ASICS updates the lab has measured lost room at the big toe. The Novablast 6 lost 3.4 mm on the Novablast 5, the Kayano 33 lost 1.5 mm and the Nimbus 28 lost 1.3 mm.
- The widths are the strength: ASICS sells a Wide of at least 11 current running shoes and an Extra Wide of 8, and its own width guide lists them as 2E and 4E for men.
- If your toes need real room, no ASICS comes close to Altra, whose road shoes average almost 10 mm more at the big toe than ASICS’s. See wide toe box running shoes.
Which ASICS has the widest toe box?
Here is the latest version of every ASICS running shoe the lab has measured, roomiest first. “At the big toe” is the number that matters for bunions and crowded toes; “at the widest point” is across the ball of the foot; toe box height is the room over the top of the toes.

Source: RunRepeat lab measurements, read from each shoe’s review on runrepeat.com, 16 October 2026. Category averages are the lab’s: 73.2 mm at the big toe across 362 road running shoes and 74.3 mm across 134 trail shoes. The lab measured the Gel-Contend 9; ASICS now sells the Gel-Contend 10, which has not been measured.
Two things stand out. The spread is small: from the roomiest everyday trainer, the Cumulus 28, to the narrowest, the Versablast 4, is 5.4 mm. And the shoes ASICS is best known for, the Kayano and the Nimbus, sit in the middle of the table, slightly under the average road shoe. ASICS is not a narrow brand. It is not a wide one either.
Newer ASICS are narrower at the toes
A new version is a new toe box. Of the 21 ASICS updates the lab has measured both sides of, 15 lost room at the big toe and 6 gained it:

The lesson for a wide-footed runner is not to reorder blind. If your Kayano 31 was comfortable, the Kayano 33 is 2.4 mm narrower at the big toe, and that is enough to turn a comfortable bunion into a sore one. The Cumulus went the other way: the 28 gave back everything the 27 took and more.
ASICS Wide and Extra Wide: what they buy you
This is where ASICS earns its reputation with wide feet. On its US site this week, ASICS sold:
- Wide: the Gel-Kayano 33, Gel-Nimbus 28, Gel-Cumulus 28, GT-2000 15, GT-1000 15, Novablast 6, Gel-Excite 11, GlideRide Max 2, Magic Speed 5, Hyper Speed 6 and GT-4000 4.
- Extra Wide: the Gel-Kayano 33, Gel-Nimbus 28, Gel-Cumulus 28, GT-2000 15, GT-1000 15, Gel-Excite 11, Gel-Venture 11 and Gel-Contend 10.
ASICS’s own width guide lists the men’s Wide as a 2E and the Extra Wide as a 4E. The measurements above are of the standard width, and ASICS publishes no figure for what its Wide adds at the big toe, as opposed to across the ball of the foot. That is a gap a brand selling this many wides could close with a gel mould and a morning’s work. In my clinic, a Wide is the right call for a bunion that rubs at the side of the shoe. For toes that are squeezed together at the front, a wider version of a tapered toe box is still a tapered toe box.
Which ASICS for a bunion, hammer toes or crowded toes
- Bunion: the Gel-Cumulus 28 in Wide or Extra Wide. It is the roomiest everyday ASICS at the big toe and the easiest to get in a 4E. If you need stability, the GT-1000 15 (73.3 mm) in Wide or Extra Wide is roomier at the toes than the GT-2000 15 (71.3 mm) or the Kayano 33 (72.4 mm). See shoes for bunions.
- Hammer toes: look at height as well as width. The Noosa Tri 16 has the most room over the toes (31.2 mm); among everyday trainers the Gel-Kinsei Max and Versablast 4 (30.3 mm) and the Cumulus 28 (29.1 mm) are the tallest, and the Nimbus 28 is the lowest of all 27 (22.7 mm). See shoes for hammer toes.
- Burning between the toes: a squeezed forefoot is the usual trigger for a Morton’s neuroma, so skip the Novablast 6, Excite 11 and GT-2000 15 if that is you. See shoes for Morton’s neuroma.
- Crowded toes, full stop: no ASICS solves this. Altra and Topo average 8 mm or more above the road average at the big toe; start with our wide toe box running shoes ranking.
Do ASICS, HOKA, Brooks or Altra have the widest toe box?
Across the road shoes in our ranking of 202 running shoes, the averages at the big toe are: Altra 82.1 mm, ASICS 72.4 mm, Brooks 72.0 mm and HOKA 71.5 mm. So ASICS is a shade roomier than Brooks and HOKA at the toes, and nowhere near Altra. For the detail on the other two, see do HOKAs have a wide toe box? and do Brooks have a wide toe box?
Questions patients ask
Do ASICS run narrow?
At the toes, slightly. The current ASICS a lab has measured mostly sit a little under the 73.2 mm road average at the big toe, and most of the newest versions lost room. At the ball of the foot they are closer to average.
Which ASICS has the widest toe box?
The Noosa Tri 16, at 77.3 mm at the big toe. For an everyday trainer, the Gel-Cumulus 28 at 74.4 mm; for trail, the Trabuco 14 at 76.3 mm.
Are ASICS good for bunions?
Some are, mainly because of the widths. A Cumulus 28 or GT-1000 15 in Wide or Extra Wide is a reasonable bunion shoe. The narrow-toed models, the Novablast 6, Excite 11 and GT-2000 15, are not where I would start.
Is the Novablast 6 narrower than the Novablast 5?
Yes. The lab measured the Novablast 6 at 71.0 mm at the big toe, 3.4 mm less than the Novablast 5’s 74.4 mm. If the 5 fitted a wide forefoot, try the 6 on before you buy it, or buy it in Wide.
Is the Gel-Kayano 33 wider than the 32?
No. It measured 72.4 mm at the big toe against 73.9 mm for the 32. The Kayano 32 vs 33 comparison has the full set of differences.
Does ASICS make a 4E?
Yes. ASICS calls it Extra Wide, and its width guide lists the men’s Extra Wide as 4E. The Kayano 33, Nimbus 28, Cumulus 28, GT-2000 15, GT-1000 15, Excite 11, Venture 11 and Contend 10 were sold in Extra Wide on ASICS’s US site this week.
Should I size up in ASICS if my feet are wide?
No. Buy the Wide or Extra Wide in your true length. Going up a size adds length you do not need, moves the flex point away from your big toe joint and lets your foot slide.
