"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."
"Innov8 trail fly in a wide are comparable as are Topo's all be it they do have a high arch. The other brands have some wide offerings but having tried most of them the above are definitely the widest in my opinion."

"the material is starting to tear on both sides where my foot bends. ... Low miles on the shoes. ... so it appears durability has decreased as well. ... It’s very disappointing."
"total lack of durability ... delicate so it falls apart when you bash through heather or bracken ... aren nearly as durable. They fall apart after really quite limited heather bashing ... fall apart bashing through heather ... When the mudtalons fell apart after one run"

"which I couldn't buy because they were -too- tight for me over the arch. ... When I tried on the Kjerag 01 I had to size up a full size for them to fit at all, and even then it was slightly uncomfortable. ... Almost two thumbs width of spare length in the front is just not doable."
"the new Innov8 last shape I find really narrow in the mid and quite long in the toe so I sent them back."
"They all fit differently. ... It was infuriating. ... So, a warning to all: Try all models of a given brand, because you can't rely on equivalent fit."

I started noticing this a couple years ago and planned accordingly. For me I have huge feet and it's hard to find good shoes. For those in my situation and like a low drop and low rise, look into Inov-8. I've only bought these shoes since early '23 and I hope they never change.
r/trailrunning • Why are so many trail shoes now high stack + high drop? ->Topo mtn racer has better grip. Inov8 has better grip also; Trailfly for hard trails and Mudfly for wet/mud.
r/trailrunning • What to choose as second shoes? ->Long reply here but I understand this quite niche problem all too well. I have a bunion in the same place on left foot but actually have skinny midfoot so always struggle to get a lockdown in 'wide' shoes. 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 width I think is in the midfoot. For example, I have a pair of precision fit Mudtalons and get a super snug midfoot lockdown but the toebox still lets my foot spread. The problem you actually have is that a lot of 'wide toe box' shoes still carry that super straight line on the inside of the foot which obviously doesn't work. Even the Prodigio Pro mentioned is quite accommodating but suffers from this to a degree as the bunion pushes the mesh out and can become uncomfortable by forcing your foot or all toes away to the side. Salomon shoes are quite bad for this, even though I suck it up and wear them as the midfoot just suits my feet. The Trailfy is the comfiest shoe I've worn in years, and I've even cleaned mine up and now wear them for walking around daily and the gym. They do a Trailtalon too if you need more softground grip, plus a road shoe. Edit to add: if anything like me, mine is just on the one foot so if I buy wide shoes, the other is super sloppy. This is why a better shape toe box works better than a wide fitting shoe in my opinion.
r/trailrunning • Help needed to find shoes that fit these feet. ->Inov8s are the answer.
r/trailrunning • Wide toe box but NO zero drop recommendations ->I've been using Inov8 TrailFlys and love them. Probably easier to get where you are. If you can find the Ultra 300 G (discontinued) in your size, that's my favorite for racking up miles in the Sierra.

r/Ultralight • advice wanted on trail runners for hiking ->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, reasonable value and regularly available with chunky discounts online.
r/trailrunning • Looking for my first trail running shoes..help needed ->I was / am a fan boy of Inov8 trail shoes but it seems like they rebrand everything in the Trailfly line up at the same time. Why can we not ever just go back and get the same model again. I do have 3 pairs of the trailfly 270 in the boxes left and they are my favorite. But it seems the 280 and the 300 are gone? I had been using all 3 and would get a couple more 300's if they were available.
r/trailrunning • What happened to Inov8 shoes? ->Inov-8 has a bunch of models in a wide size now. Even the older models I use have a lot of room for my toes. Durability is fine I think, compared to what I read about Altras.
r/Ultralight • advice wanted on trail runners for hiking ->I'd say yes (not having used the latest models personally though). I find mine very comfortable.
r/Ultralight • advice wanted on trail runners for hiking ->I can also confirm the durability of Inov-8s!
r/Ultralight • Another discussion on shoes - please help ->Inov-8 trailfly ultra g 300s. I have 500+ miles on them through all type of terrain and they still have a ton of life left in them
r/trailrunning • What’s the best trail running shoe you’ve ever owned and why? ->Don’t know of any places that offer that kind of support but you could try inov8. They’re outsoles are supposed to be tough. The ones I’ve used fell apart before the sole showed any wear. They’re sizing isn’t very consistent though so worth trying in a shop if you can find them.
