Comments: I keep 2 sets of shoes active. One is for daily training (5-9 miles per run) and another for the long slow runs (9-18 miles) which are also used for race day events, which are mostly full marathons (life time #21 in 3 weeks). I got these for the race day events. At first they felt really great. My per mile pace on cruise runs when down and my feet felt good even after 10 miles. After about 2 weeks, they started to do strange things somewhere around mile 7. They start to feel very tight in the toe box and then the arch support seems to move around. Sometimes I re-lace them and the problems go away for a while. Some times this only increases the pressure on the top of my metatarsals. These are great for half marathon or lower. I will not use them for a full marathon as they just get to strange when going big distances.

Comments: This is a very comfortable and lightweight shoe. The upper is great. The sole is soft and flexible, it reminds me of nike frees, but with some "support". It doesn't seem like the shoe will hold up past ~350 miles. I've got a 100 miles on them now and they still feel good. All in all, a good buy.

Comments: Got this shoe to complement my NB1260v3's. Like the light weight,ample cushioning,heel drop,color and fit of the shoes. I have "B" width feet, pronate moderately and run about 25-30 miles a week. These definitely run narrow for a "D" width. Heel fit is great-no slip! I also have a flat arch, but feel that these shoes give me good support on the medial side. Will probably use for shorter/tempo runs.

Comments: I've been a runner for over four decades, so I have a bit of experience with running shoes. Now that I run "midfoot style," I've had to select midfoot running shoes. So when the Vibram Five Fingers or the NB Minimus offer too LITTLE support, go up a bit to the N.B. 870...it's perfect! I used the N.B. 890 for a while and I like the 870 slightly more, probably because of the support for the mild pronator. I've done repeat miles in this shoe and it's just fine, although for speedwork, I prefer the awesome N.B. 1400. So yes, this is an endorsement.
