My 245s arrived yesterday and I took them on a 14 mile training run over mostly hard packed, rocky terrain, here are my early impressions. I am impressed with the traction, comfort, and locked in fit. I already prefer them over the MT110s. The trailrocs fit my low volume feet perfectly, just like the Minimus last but a tad bit more room in the toe box. I purchased the same size I wear in Minimus Trail and the fit was spot on.
Traction was nice all around - from the hardpack, loose gravel, mud, and soft pine needled track I have no complaints. The upper was 'breezy' and after a small stream crossing they drained and dried pretty well. I do like the mesh upper more than the also nice synthetic 110 upper. I did not have any debris catch or snag the mesh on my run. Also, I did not notice any debris getting through the thin mesh yet or any hotspots. I absolutely love the outsole on this shoe! I just hope it's durable enough to justify the high price tag. I believe it will put the 110 to shame in this category.
In regard to weight, I didn't really notice a difference between these and the 110s. The lower 1mm drop of the trailrocs was not noticeable to me either. I did notice a difference with lack of soreness after my usual run which I attribute to the additional cushioning of the trailroc. Or maybe it's just because the EVA foam of the 110 was crushed after the first 30 miles on mine.
Complaints - the laces. I guess NB has just spoiled me. Those thick laces just don't come untied. I had to double knot the inov-8 ones. Toe bumper is pretty much not there, it could be beefier. I also wish the tongue was gusseted higher up, it doesn't want to stay put.
Overall I am very satisfied with this purchase. The fit really is spot on, and that was one of my biggest concerns. Now if the durability is there this could be my all around go to trail running shoe. I'm excited to take them out on my long run Saturday.
