"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."
"Xodus Ultras were also a bit too narrow in the toebox for me for anything over 50k."
"But IMO they won't fit high volume feet."

"The trailfly is firmer and more ground feel ... with low drop ... if you've not run low/zero drop, then you need to take it easy an acclimatise."

"They’re sizing isn’t very consistent though so worth trying in a shop if you can find them."

Yeah I've gone to a shop to try them on. I've worn the Salomon Sense Rides before so going for that would be a safe bet. The other two models do also appeal to me as I'm interested to try Innov8's technology, but wasn't sure how comfortable that pair is on tarmac.
Sense Ride is the most comfortable, mainly because I've worn them before. My feet aren't used to Innov8's make and its relatively lower heel drop but I'm contemplating giving it a shot - only if this model is suitable for pavement to trail running though.
They 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.
I feel the 'new' range is just uninspiring and feels old fashioned. I tried the Trailfly Speed which was heavy with a dull foam. Standard Trailfly was heavier with more dull foam! They just aren't competitive with other shoes out there. La Sportiva Prodigio shows how a modern all round trail shoe should be (and it's been a massive success). It's a shameas they used to be one of my favourite shoe brands, I went through 4 pairs of the G270's loved that shoe. Numerous Roclite, Mudclaw, X-Talon. I just don't consider them as an option any more. I live in the Lake District and not many of my friends wear them either any more. Mudclaws used to be the go to. See a lot of VJ, Terrex, Nnormal, La Sportiva and Hoka now.
Everyone is piling on the Topo recommendations and I agree they're a great option. Just for some variety I'll suggest Inov8 though because I prefer my Topos for hiking and my Inov8s for running. The Trailfly comes in standard or wide, has a foot shaped platform just like Topo and Altra and is 6mm drop. It also comes in 4mm drop (Trailfly Speed) and will be available in 0 drop (Trailfly Zero) this season. Either Inov8 or Topo will blow Altra out of the water for durability in my experience.

Just for statistics: I still really like them. After the updates to all the product lines they fit my feet even better. Luck of the draw I guess. First used the Trailtalon 235 in 2019 followed by two pairs of the Trailfly G270 V1 and a Trailfly G300Max. So I never wore the fell running models of the glory days everyone seems to miss so much. Now using Mudtalon Speed, Trailfly Speed and Max Models. They fit loose in the heel which you can counter with adjusted lacing. All of them are extremely durable with good grip. I also like the wider toe box. The look is quite dated and uninspiring though.
I 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.
Inov8 Trailfly variant. I have the Trailfly Speed. The most important aspect is the depth and also the size of the lugs. 3-4mm should be enough and should not be noticeable on the asphalt.
I have trail fly v1... I like them but feel like they don't grab my heel like they could. A little bit prone to blisters on outside of my heel if I do long runs in them, but it's tricky cos they're really nice to run in, and up to that point really comfy. Weird thing is I have tried both trail fly speed and trail fly max, and both are better on my heels despite going in opposite directions from the base model. Keen to try the V2 and see if it's any better
u/ProperLow3692, also would recommend Inov8 My main gripe is that some of them have some unwanted arch support. That being said, I have some Trailfly Speed's in wide and the toebox is absolutely spacious to the point of making me wonder if I actually prefer only a slightly-wide fit. Keep in mind that their increased-width toeboxes are only part of their recent models and their older ones (mostly out of production) are slightly narrow.

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.
