Comments: I love these shoes. Context: This is my first experience with a racing shoe and I use mine as my daily trainers. I always run in socks because I think it keeps my shoes stink free longer. That being said, yes the upper is waaaay too scratchy for bare feet. I tried them in my regular size 9 (snug) then sized up by a 1/2 like I've seen recommended because I was concerned they wouldn't stretch enough and they'd rub up the pinkies on my square feet. Given that I don't alternate them with another shoe I think that was a good call. After about 370 miles there's more than a thumb width distance between the tip of my big toe and the tip of the shoe and they're starting to feel a little loose when I'm going up inclines. That's my only "complaint". When I started running it was with a few iterations Brooks Glycerins then I graduated to Saucony Kinvara 4s and now these. Owing to the firm forefoot I believe these shoes made my feet and achilles stronger and helped improve my form! And yes, there was a period of time where the 1400's didn't feel like they were working for me but I stuck with them et voila! The dreaded 10mm dop (versus the 4mm on my Kinvaras) was a non-issue because I naturally adapted and moved from midfoot to forefoot striking. If you're a lifelong heel striker go easy or you may be risking knee problems, the heel is that soft. It feels weird to walk in them. What minimal rubber (or whatever) sole wear I have is mostly under the forefoot with very little at the outside edge of the heeI (I'm a mild supinator). The midsole shows abrasion wear around that diamond shaped expansion hole. That seems to have gotten worse lately and I've noticed that my feet are feeling more tired after runs so it's probably tim e for a new pair. Oh, I set my 10K PR in these. I love these shoes.

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.

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.
