I ran a 50 mile ultra in technically difficult terrain (7k gain). The first half in my Innov8 Terrafly 303 feet felt great but seam of shoe tore laterally at the sole junction. Ran the second half in the TrailRoc without trouble. These are both great shoes comfortable for long distances. The former is best for light trails (less rugged tred) and the TrailRoc best for more difficult terrain. They have a slightly more aggressive tred but have better reinforcement where the Terraflys do not. My feet blister easy and callouses I thought were needed for protection prior to my experiences with Innov8. I've not had a single blister since and painful callouses have regressed. I use a slightly expensive sole insert from the Walking Company to provide a little extra cushion. Shoes allow for foot swelling that occurs on long runs. Very supple with no break in needed. Provide excellent sensory feedback. They are as minimaliistic as I can get and strengthen feet without beating them up. No experience on road with these shoes. The TrailRocs are my perfect trail shoe. This is after much trial and error with expensive Salomans, Brooks, and Altras.

The way this shoe fit and felt I was blown away considering it falls within the 2-arrow portion of Invo-8's system, it was snug yet I had plenty of room in the toe box, very comfortable ride. Here is the negative part though, don't get these bad boys wet under any circumstances, the lugs on the bottom don't have invo-8's trusty grip like lugs, these are smaller and have no grip, you will slid all over and risk getting injured if you do, if it wasn't for that these for me would have been a keeper.

Rock plate protects my foot without being too heavy. I usually wear 4 mm drop shoes but find less stress on my lower legs with the 6 mm drop on these shoes. My first long run in this shoe was a 50k and they felt great on my feet after I was done. I didn't even take them off right away.
I went 1/2 size up on these which was recommended on the Inov-8 website, however, they probably would fit better at the size I normally wear. I like them a bit big for the long runs where my feet swell anyway.
Honest reviews on Inov-8 Trailroc 255 Trail Running Shoe
Love these Inov-8 trailrocs! Out of the box, these fit like they were custom made for me. This is my second pair of the same shoe. The first ones I wore out from so many miles.
I'm a Spartan racer, and I have worn these for my last 5 races. They are so light that I can barely feel them on my feet, while at the same time being sturdy enough to handle rugged terrain. They grip well on wet or muddy surfaces. When going through water, they release the water easily so I do not feel bogged down. Going through mud is another story, of course its going to retain some dirt if you submerge them, but you could get the mud seals if you needed them. The laces tie tight and don't slip.
I also own a pair of trailroc 245's which are a lighter duty sole. I use these for training or for less rugged runs. I've found they don't grip quite as well on slippery surfaces and you can feel the terrain a lot more in them compared to the 255's. Depends on what kind of run you're doing which will influence your shoe choice.
I had some Soloman's which were a lot heavier than the trailrocs and did not release water. I use those for hiking, mountain trails, and for runs where there will not be much water.
The Trailroc 255 is my shoe for trail running. Will keep buying them when the current ones wear out.

Shoe fits great with a little extra room in the toe box. Very comfortable just wearing around the house or doing errands. Grips great running on hard packed sand, loose sand, gravel, and paved roads. Only cons I've encountered was that the tongue slides to the outside of my feet during times of extended wear and that I wish the shoe dried a little quicker. I will definitely consider buying from this brand again and possibly the same shoe again.
