Comments: Feels great! Light, soft and responsive. Problem is that the traction in the the forefoot fell off after a few races and workouts. Does New Balace sell the little traction nubs I could glue on myself?

Comments: Very well-built shoe, good grip and a "silent" outside that doesn't make much noise upon impact compared to other racing flats. The upper mesh seems solid and not as fragile as with Adizero Hagio as a comparison. I ordered half a size up compared to Hagio and fit is good, there's some room in front of the big toe but like Chas, NC is stating below, not much space over on the sides. Toe box is somewhat low and somewhat narrow but half a size up compared to Hagio solved it for me. The shoe is overall very comfortable, soft but offers some stability and surprisingly a lot of cushioning considering the low weight. I would not hesitate running a half marathon in these, for a full marathon maybe the forefoot is a bit too thin to appeal to me. Good looking, well-built, allround racing flat that I definitely would recommend!

Comments: I'm 6'2" 180 lb. supinator who got these yesterday. I have tried a host of lightweight trainer, marathon race shoes including Mizuno Ronin, Nike Lunaracer and Flyknit Racer, Adizero Hagio and Adios and Karhu Flow 3. They are all great shoes but for some reason one or more of their support features left me feeling that I was battling the shoe to get my stride to turn over. The 1600 has a narrow fitting but comfortable fitting upper out of the box. One big plus is the way the upper clings to the heel and Achilles. Very snug. The others have always required creative lacing at the top that resulted in excessive pressure on top of my foot. I ran 11 miles in the 1600 today with ten short intervals at 5k pace. The upper broke in quickly and loosened significantly by mile 5. The midsole is the best feature of the shoe. Firm and responsive but not harsh. Just the right amount of flex. No wave plate, fulcrum or sprint web to fight with. Just good, old-fashioned EVA leaving my feet free to work without constraints or "help". They reminded me of my old favorite, the Adizero RC with a slight bit more cushion. No issues whatsoever. This is a big winner with me. A great old school shoe that can take on anything.
Comments: I wanted to love this shoe. The new revlite cushioning is second to none, great protection in a flat of this weight. It feels to have a pronounced heel, I could definately tell it wasn't a zero drop shoe. The downside is it just didnt fit my foot, the laces started too distal on my foot and I got a lot of rub at the base of my fifth metatarsal. Tried a bunch of different lacing styles but I couldn't shake that pressure I felt, so I'm sending them back. I hope they work for others, because the cushioning is fantastic, the weight is just right, and outside of that lacing issue the upper is comfortable. I'm sticking with my Zoom Streak XC3/LT as my flat for now though.

Comments: This is a solid racing flat. I was worried about the unusually (for New Balance) narrow forefoot, but the mesh is comfortable and doesn't squeeze me. If you are between 2 sizes, take the larger of the two. There will be some room in front of the big toe, but everything else will be Cinderella. I normally race in the Adidas Hagio or the Inov-8 Road-X 155--both great shoes. The MRC1600 is like a hybrid of the two. Versatile and durable as the Hagio, but also flexible and lighter than light like the Inov-8. The heel cushion feels like a little more than the advertised 6mm H/T drop, but the
Revlite is a nice, responsive midsole material. This will be my shoe for 15k to road marathon. However, they would work great for track days, road tempos, and shorter races too.

Comments: An okay shoe, with some pretty firm cushioning. Unfortunately, the pretty thin forefoot doesn't always offer the most protection, especially on some rocky trails. However, I was a fan of the lower H/T drop, even if the last otherwise seems to be kinda narrow, which seemed to prevent adequate toe splay. Also, sole durability isn't the greatest. Nonetheless, a ~6.5 - 7 outta 10.

Comments: I have some seriously narrow feet and long toes, so this won't be relevant to everyone, but I love this shoe. I'm a 2:48 marathoner doing 55-65 miles a week on average. After running several marathons in the Nike Lunaracer, I wanted something a little more traditional and firm. The Lunaracer just started feeling to pillowy as I transitioned to more minimalist footwear in my training. In my case this means mostly NB Minimus Roads 10s, and Kinvaras. I haven't raced in these yet, but I've done a few hard workouts, including 17 miles with up to 6k intervals at race pace, and they performed beautifully. Just enough toe room, just enough cushioning for the long haul, just enough heel drop(around 6mm supposedly), really overall, just enough is sometimes exactly what you need.

Comments: I got these shoes about 3 weeks ago to give myself a little more cushion for longer runs then my MR00's were providing. I was running more then 5 miles and getting soreness on my feet. Not arches, just simply the muscles in my feet. So I decided I would try these. The first few runs, they were a little tighter than I have been used to but once they stretched out they have been great. The only complaint I have is running down hills they seem to shift around on my feet a little bit. NB recommends wearing them tight to envelop the foot. I don't think it's a sizing issue necessarily but overall I love them almost as much as my Minimus Road zeros.
