Despite whatever impression you might get from my wife or the shoe rack in my closet, I'm ultimately a two-trail-shoe kind of guy: I want a lightweight pair for daily training, and a heavier but more cushioned pair for recovery days and long runs. For about the last 8 months I've been slowly reducing the weight of my heavier shoe. I started out in something a little over 12 oz, and later went down to something in the 10-10.5 oz range. At just under 9 oz for a men's size 9, the Brooks Pure Grit is the next step in that progression for me. And the short version of the story is, I really like it a lot.

| Looking no worse for the wear after 50+ miles |
If I could only write one thing about this shoe it would be how
comfortable it is. It is easily the most comfortable trail shoe I own,
and statements that it "fits like a sock" are no exagerration: snug in the heel and midfoot, and roomy in the toe box, just how I like it. The entire upper, including the support overlays, is very soft and flexible. It really does a good job of hugging the foot without impeding natural motion and articulation. A lot of times on my recovery days just putting on my shoes feels like a chore. That has not been the case with the Pure Grit. It almost feels refreshing to slip them on when my legs and feet are feeling tired.
The downside of a soft flexible upper is that I find I have to be more careful with lacing. If I don't get it right then my foot moves a little too much and things get sloppy. Dialing in the lacing with the Pure Grit did seem to take a little bit longer than usual. The elastic band over the top does interfere with lacing sometimes, so I will probably cut it off even though it hasn't caused any discomfort.

| The entire upper is well-ventilated |
The ride of the Pure Grit brings to mind a mid-weight
road shoe. The flexible outsole makes for an effortless transition onto
asphalt, rock, and other hard surfaces. A lot of my trail runs include an
approach on pavement or dirt roads so I definitely appreciate the multi-surface capabilities. For example a recent 16-miler that I ran in the Pure Grit involved about two miles of pavement, three miles of dirt road, and the remainder on single track. The shoe felt great the entire time. I also have found turnover to be very good, and that combined with the weight make it hard not to push the pace on smooth trail and cruiser-grade downhills.
The cushioning is ample but firm.
I don't mind soft cushioning in a road shoe (think Saucony Kinvara)
because the compression is mostly vertical. However I find that overly soft
cushioning in a trail shoe makes for an unstable ride: the soft cushioning is simply unable to resist the rotational and lateral motions that result from running on uneven surfaces. Fortunately the Pure Grit doesn't suffer from
any of that. On the other hand, there is enough cushioning present to
reduce ground feel a little bit and make the shoe somewhat less
responsive. On more technical terrain it doesn't have the crisp, tactile handling of shoes like
the New Balance MT 101, for example. The cushioning did seem to firm up a little bit around 20-30 miles.

| The radiused heel is intended to reduce heel striking |
The Pure Grit has a number of features that are intended to encourage
"natural running": the split outsole fore and aft, the radiused heel, and
the strike pod in the center of the outsole. The Pure Grit does not
impede my stride in any way, even on steep downhills, but how much of that is due to these
features versus the 4mm heel-to-toe drop I couldn't say with any certainty. And from a performance perspective I don't
really care: as long as the shoe doesn't get in the way, I'm satisfied. I don't know to what extent these features increase manufacturing cost, however, so on that basis I might be inclined to leave them out.

| A simple but effective tread |
The outsole is constructed from a (mostly) single piece of what appears to be a very durable rubber compound. I prefer uncomplicated, robust lug patterns on my trail shoes because I feel like they wear better and are more effective. The Pure Grit definitely meets that standard. The tread is not as grippy as shoes like the La Sportiva Crosslite but I have not found it to be inadequate either. It has performed very well on the often-rocky Santa Fe area trails, and holds its own on snow. No issues with Kathoolas either. I do wonder if some weight could be saved with lighter (albeit less durable) material in the center portion of the outsole, similar to the New Balance MT 110.

| Testing out the chains on fresh snow |
In summary, I chose the Pure Grit as a heavier, more cushioned complement to my daily trainer (currently the NB MT 101). In that role I am very happy with it so far. It is not the most nimble shoe out there, but for the slower paces of my
recovery and long runs it is exactly what I'm looking for: a smooth comfortable ride but without the clunkiness and weight that one would normally associate with that category of shoe. So there's a very good chance I'll be lacing these up at Leadville. The Pure Grit also would make a great all-around trail shoe for someone who primarily runs roads and is used to the ride and handling of a road shoe. It has most of the comfort and runnability of the Brooks Cascadia but in a lighter and lower profile package.
As for the "natural running" aspects of the Pure Grit, I view the whole natural running thing as a means to an end. If it improves my running, great, but "running naturally" in and of itself is not one of my goals. On the other hand, I do like the fact that the natural running movement is driving innovation in shoe design, and the Pure Grit is very much the result of that. Yes there are a few things I might tweak but those are all minor.
Lastly, I know this shoe has been likened to the Saucony
Peregrine so I wanted to give my thoughts on how they compare since I have spent a little time in that shoe as well. On paper
they are quite similar, both in weight and stack height. However, I feel like they followed opposite
paths through design space to get to that similar end point. As I
mentioned the Pure Grit rides very much like a road shoe, and overall it
does come across as a road shoe that's been beefed up with a more tractional outsole and slightly reinforced upper. In
contrast the Peregrine seems to me like a canonical 11-12 oz trail
shoe that's been lightened and had the heel trimmed down. It has many of the characteristics one might normally associate with heavier trail shoes: more substantial tread,
increased upper protection, and somewhat less flexibility. The Peregrine also feels a little higher off the ground to me. But don't get me wrong: I think both are excellent choices in the mid-weight trail shoe category and I wouldn't be unhappy with either.
