Comments: Very lightweight fast shoes! I'm usually pretty good at estimating my pace without checking my watch, but with these shoes hitting speeds is so effortless that I'm almost always going at a quicker rate. They are flexible enough that the 9mm drop does not impede fore-midfoot striking, but provide a snappy response. The ride is firm, as you may expect in a racing flat, but not overly so and they could be worn for long distances. Because of the odd shaped cutouts under the metatarsalgia (balls of feet) I did develop some blisters that I have not experienced with other shoes - even of a lower stack height - when doing runs over 10k distance. The outsole, however, is very durable, and should last a long time. I have used it on some light dirt roads and it provided great traction.

Comments: My new favorite and probably best shoe I have worn in a long while. They absolutely disappear on your feet and have the perfect combination of cushion and responsiveness. Completely agree with others in ordering a half size bigger.

Comments: I love these shoes. After switching over from the Kinvara line, I was a bit nervous about the 9mm drop, and was disappointed with the rough interior of the upper. After a few runs (with lightweight socks) I had red, irritated areas on the outside of my small toes. BUT I kept with it, and after 30 or so miles the uppers softened considerably and no more irritation. I now consider the 1400v2's to be the most comfortable and best shoes I've ever run with.

Comments: I love this shoe. I ran a 5k race the first time I ran in them. Very comfortable. I replaced the insole with Dr. Scholl's Active and probably doubled the weight of them. I've had two foot surgeries on each foot (Hallux Rigidus) and so I'm very choosy about my footwear. I got the M1400v2 a half size larger than my normal size and the fit is excellent. The toe area isn't cramped at all.

Comments: What I like about this shoe: lightweight yet great cushioning (I've only taken them up to half-marathon distance and my legs felt great), durable outsole, breathable, forgiving for heel-strikers. What I don't like about this shoe: the massive blisters than I get on my pinkie toes (I don't have wide feet and I'm in the correct size). A slightly wider forefoot and this would be my go-to racing shoe.

Comments: I wanted to love this shoe. The NB 1400 v1 was the finest all around shoe I've ever run in - great for training, racing at all distances up to 26.2, and dirt trails. Sadly, version 2 falls short of the original in multiple respects. First - and let's get this out of the way early - this shoe is NOT lighter than v1. It's heavier. I weighed them side-by-side against my last pair of still-in-the-box, I'm-saving-these-for-Boston v1's. The v1 weighed in at 6.3 oz, the v2 at 6.5 oz. Both size 9D. And the v2 feels heavier on the foot. It's softer, less responsive, and just doesn't feel as fast as the v1. It also feels somehow chunkier in the midfoot, making it harder to cleanly forefoot strike. And while the mesh looks lighter, it is in fact less breathable than the prior version. And finally, v2 is both narrower and lower volume in the toe box. My little toe gets squeezed and I developed a hot spot on top of my big toe on a 13 miler this weekend. So, my unfortunate conclusion is that New Balance has essentially ruined what may have been the finest and most versatile neutral flat ever made.

Comments: I love the 1400 version 1, but I have to agree that the version 2 has a really "scratchy" upper. I have about 25 miles on them and they still cause irritation on my toes even wearing socks. Stocking up on the version 1 for now.

Comments: I have to take back what I first said about this shoe. Originally I was pretty upset that I wasn't able to comfortably wear these shoes sockless like I do in the V1. The new upper material was just too scratchy on the tops of my feet and I always run sockless. With winter weather forcing me to wear socks like a normal person I found that sweet spot. After a few runs the upper has softened up considerably. The shoe feels firm in the forefoot, but nice and plush in the heel. I'm so happy I gave it a 2nd chance. This is now my go to trail/road shoe. The outsole compound is super sticky even in wet conditions, so even though there's no lugs or aggressive tread for trails, it still sticks really well.

Comments: Marvelous shoe. This is a racing flat, and fits snug, similar to the Brooks T7 as a point of reference. I wear an 11.5 in most shoes, and wear a 12 or 12.5 in the MR1400 v2. The good news is the shoe is incredibly light....my 12.5's are still incredibly light. The feel is perfect for the road, and the shoe feels fast. New Balance has a winner here. This is my racing shoe for 2014.

Comments: The 1400 V2 does not necessarily fit smaller. Much of the fit issues are due to the new insole. Since I swap the insole out for a Superfeet Black, the V2 fits me in the same size as the V1. I'm pleased with the update and happy I opted for a pair of the V2 as opposed to a closeout V1.
From: Jeff, Scottsdale, AZ, USA
Comments: Upper is stiffer than original 1400 and the fit is snugger to forefoot. I wear the 1400 without socks and the upper fit on V2 is less comfortable because of stiffness causing rubbing on top of my foot. Right out of the box they felt incredibly light. A noticeable difference in weight from V1. It has a bit less of a cushioned feel to me when run back to back with the V1. Looks like there is less Revlite foam in the heel to save more weight. My opinion is buy all the V1 1400 you can. This update is not better than the original even though it's gotten lighter.

Comments: Nice shoes but don't get fooled by NB marketing. This shoes fit way smaller compare to the previous version. It might be 0.7oz lighter in size 9 but if you needed a size 9 in MR1400 you will certainly need a size 9.5 in MR1400v2, the comparison is biased and you might not shave that announced 0.7oz.
