"only inov8 fits"
"Inov8 Trail Fly do a wide fit for what is already a wide fit shoe. ... They are the only thing I have found that is wide enough comparabley to an Altra."
"The Inov8 Trailfly and their new range works well here. ... I'd actually go for the standard fit over wide as the toe box is already foot shaped. ... the toebox still lets my foot spread."

"I’ve been wearing Inov-8s for 15+ years for trail and fell running and even moved to them for XC races when achilles injuries meant I could no longer wear spikes. ... Always done the job for me"

"Inov8 aren't that wide apart from the toe box. ... I tried their wide fit and found trabucos to be wider around the arch of your foot. ... I have flat-ish arches so find it very uncomfortable if my foot ends up collapsing over the end of the shoe."

Adventurous-Hyena-51 1.0They still/again have zero drop trail runners? Trailfly zero, mudtalon zero. Trailfly speed is 4mm drop. So I'm not sure if you're looking in the right place?
Topo mtn racer has better grip. Inov8 has better grip also; Trailfly for hard trails and Mudfly for wet/mud.
Denning76 1.00 drop with double the stack of the previous pair, so a completely different shoe.
I’d have to check but the ones I saw definitely had far more stack. As for the mudtalons, the issue has never been the drop but the total lack of precision and durability compared to the mudclaws and xtalons they were supposed to be replacing. It’s rearranging the deck chairs in the titanic.
exzachtlee 1.0I love my Inov8 shoes, and think their new lineup is great. Anatomically shaped, regular and wide options, comfortable and stable, and there are models for all diff terrain (same rubber compound). They seem to be misunderstood, these days. The closest replacement for the Roclite 275 v2 is the Trailtalon Speed (6mm lugs, similar midsole stack, 6mm drop instead of 8mm). I’ve run multiple 100mi races in Trailfly Speed and Trailfly Zero **Roadfly** has a 0-2mm tread **Trailfly** has a 4mm tread **Trailtalon** has a 6mm tread **Mudtalon** has an 8mm tread Of those models, the variations are with drop and stack height following drop and stack (without the tread depth): **Zero** (i.e. Roadfly Zero) is zero drop, 18mm **Regular** (i.e. Mudtalon) is 6mm drop, 24/18mm **Speed** (i.e. Trailtalon Speed) is a 4mm drop, 17/13mm **Max** (i.e. Trailfly Max) is a 6mm drop, 30/24mm
Try out Inov8 shoes. I have great results on wet rocky terrain. I like Trailfly Speed and Zero. They’re foot shaped wide toebox. They also last 2-3x as long. Second choice would be Altra Timp.
flingtoad 1.0Inov8 has several zero drop models, but they may not be available everywhere. In the U.S., I can get Trailfly Zero, Roadfly Zero, Trailtalon Zero, and Mudtalon Zero. I have the Trailfly Zero (Wide) and they're pretty good. There's plenty of toe box space for me. Mid-foot and Heel are less generous, but they work well for my foot shape. You may need to go up a half a size. They're a little on the expensive side.
marieke333 1.0Inov8 Trailfly zero or Trailtalon zero.The wide version is nicely footshaped. They lock wel around midfoot and heel, good tongue padding (I have a narrow heel so I wear them.tight and don't feel te laces at all), very comfortable insole, durable graphene outsole. (edit: i have the regular versions, not the zero's)
If you don't have a very wide heel/midfoot you could also try the Inov8 Trailfly or Trailton wide models. Foot shaped, wide at the front and with a durable graphene sole. Both available in zero drop versions. I went from the Lone Peaks to these models and couldn't be happier, they better hold the midfoot in place on oneven trails if you don't have a beefy midfoot.
oeroeoeroe 1.0I've been liking the new Inov-8 Trailfly Zeros in wide. Vivo shoes fit me decently well and these seem similar fitwise.
I've liked the new Inov-8 Trailfly zero a lot. Also got a shell from Dynafit, one of the few options which is designed to fit over the vest.
I don't know about Nordas myself, but about Inov-8. They quite recently brought back a zero-drop model, and they have wides available. I also get heel slippage with Altra 9+ wides, Trailfly zero has nice and snug heel. Trailfly Zero is basically same width in the toebox area, but shaped differently. Altras rub my big toe, Inov-8 squishes my little toe. For the same shoe size Altra is a bit longer and more voluminous, it could be half-a-size difference.
I'm loving their new Trailfly Zero. I liked the classic G270, but it was narrow in the toebox, while Zero in wide is just perfect for me fitwise, and I like the slightly stiff but low stack, I find the traction quite good on varied terrain. I dunno, I'm not sure what I'd like in it to change. They are ugly, but I can live with that. I'm Finnish, I think they are one of the more common brands here, but behind the main names Hoka and Salomon. VJ and Altra seem to be quite popular as well.
Inov-8's new lineup has wide options for every shoe. The one's I've used have been super durable shoes. I like the zero, but some of their thicker shoes with drop might align with your preferences better. Offensively ugly, but really good shoes. For sizing, always go by the bigger foot. Perfect would be to find a friend with opposite problem and split pairs, but that's pretty unlikely..

Rate_Pretend 1.0Maybe give Inov8 Trailfly Zero a shot, too. I am currently, coming from Xero Scrambler Low and Topo Runventure 4. Wide toebox, I prefer the build (outsole, foam, fit) to my Topos.
Thorias25 1.0As I wrote elsewhere, go for inov8 trailfly zero. Exactly what you are looking for.
Go for inov8 trailfly zero. Great toe box, no drop, thin sole.
yizong127 1.0I got the Trailfly Zero, I'm sold it's a really solid shoe but holy cow the boomerang footbed does NOT work for me. Feels like I'm chewing a bit of fat with my feet, not as stable as I'd like and doesn't feel as efficient at all. Swapped the insole to a vivobarefoot one and all is right again👍 I can say the midsole is real nice now I can actually feel the responsiveness.
inov8 Trailfly. You've got the Trailfly Speed, Trailfly Max, Trailfly Zero or standard Trailfly all with either a standard or wide variant. I'd also add that their last is as wide as the old Vivobarefoots and wider than the newer Vivos. Comparable to the Altras that I have in a similar size. I measured these by overlaying the insoles on top of each other.

DeskEnvironmental 0.2I just bought their trail running shoes, zero drop, and they’re way too flimsy for the technical trails I run. I can use them for walking the dog.
