That being said I love the 790s and was very concerned about my running shoe future since they stopped production many months ago. I knew the NB was building a new low profile trail racer and assumed that it would be under the guidance of their outdoor “ambassadors” Tony Krupicka and Kyle Skaggs, so the prospects for a great improvement were certainly exciting. I first heard about and saw (on the internet) the 790 replacement, the MT100 in the late spring. It was being advertised as even lighter than the 790. In Leadville this July, Tony was gracious enough to show me some of the preproduction MT100s. The extremely simplified design was cool, but my main excitement lay in the slightly built up forefoot protection plate and one-piece (non overlay) outsole. Finally, I got a pair from my New Balance rep Shane on my 22nd birthday. I have been blasting around my local trails and non-local mountains in them for about a month and a half now and have nothing but positive things to say about the shoe.790 vs 100
The outsole/forefoot plate are delivering as expected, with the same amount of flexibility and surefootedness provided by their precursor, but in a more useful (grip on sand and it looks like they will tear through the mud as well) and protective package.(Notice the orange outsole "bumps on the 790 as well as the midsole on the outer midfoot getting destroyed due to a lack of outsole and the corresponding "corrections" in the MT100 on the left)
The upper is about as simple as they could make it. Lightweight mesh, non-padded tongue (Yay!), and plastic and metal ornament free; it fits my foot snugly but is not too tight by any means, simply an elimination of the slop I cavalierly complained of earlier.
