Anyone her own the New Balance MT100?

I absolutely love them. Got a pair in early November and have been wearing them for all my trail runs - 4-5x per week for 80-90 minutes on pretty technical rocky/rooty and steep mountain bike trails. This has included in snowy/icy covered and wet/muddy conditions.

I have also worn them on a grass cross country course in muddy/wet conditions (including one run of ~20 miles) and they did great there too.

Have not used them on the roads too much though. Just a mile here and there and for one short (~2.5mi) road race that was on a steep uphill/downhill course (wore them for the extra traction and they worked well).

I was really surprised how well the rock plate works. Thought for sure my feet would get beat up in such a light shoe on the really rocky stuff, but they hold up fine.

Don't know if I can help you on the fit compared to other NB shoes -- I usually wear Asics. The fit on my 12.5 NB 100s feels pretty similar to my 12.5 Asics Hyperspeeds (NB may feel just a tad more snug). Don't think they have much of an arch to them -- that's not something I really look for...

Hope that helps... let me know if you have any other questions...

i've been running for several years in the NB 790 (women's model; 6.6 oz) and have recently picked up a pair of WT100s (6.0 oz). i can't compare with the models you list, but here's my take vis a vis the 790. they have the same heel-to-toe drop, which is less than anything i've experienced in a trail shoe, but is not zero (11 mm?), and both models are nicely slipperlike and low to the ground. i need to switch out the insole on the 790s for something other than the pancake-flat thing it comes with, and the 100 has that same flat bit glued in. however, the arch of the 100 has a bit more shape to it to begin with, so i'm okay with the insole as is, but you might do well to try on a pair before buying. i believe finish line sells the men's model (but alas not the women's) at a very attractive price ($50).

the 100 is designed for midfoot strikers -- the most robust portion of outsole is on the lateral side of the middle of the shoe, rather than the heel (although "robust" is an exaggeration of the tread -- i suspect if you log many road miles in these things, the nubbies will be worn down flat in no time). if you're a heel striker, you probably won't be happy, but if you land midfoot, it's great. i've only had a chance to try them out on snowy trails (it is winter, after all), but i was very happy with (1) how warm my feet remained, despite the very airy construction of the upper, and (2) how the tread handled icy patches and kept me from slipping unduly on frozen ground and fluffy snow.

i'll be racing a warm-weather trail marathon in february and will be doing it in the 100s.

Thanks guys, they're sounding better and better. I've logged more than a couple of miles im Hyperspeeds, and if these have a similar fit, I think I'll be fine.

I'm definitely more of a midfoot striker- I very rarely put much wear on the heels of my shoes, much more up front than anywhere else. I do tend to overpronate more on my right side than my left (which is why I'm trying to get on softer surfaces...) but as long as they aren't completely hollowed out under the arch, I think I'll be fine. Thank You!
