I've been wearing these MX20 Minimus training shoes for my workouts for about 2 1/2 months, and I'm very happy with them.  I've worn various NB cross trainers in the past that I've been happy with, but this was my first foray into the "minimal" shoe category.  I wasn't sure if I would like them when I ordered them, but I'm very happy with them.

I wear these NB exclusively for working out in a gym environment.  The only running I do in them is 5-10 minutes on the treadmill, either a warmup or a few intervals.  I would not try running in these shoes on pavement as the sole is very thin and feels soft and I'm guessing they would probably wear out quickly - they seem to be made for mostly indoor use.  These aren't running shoes so that may be obvious, but in the past I've occasionally used cross trainers for short runs outdoors and I won't be doing that with these as I'd like them to last.

I don't do cross-fit per se, though I guess my workouts do sort of resemble it.  I do mostly a combination of calisthenics, weight training, and some cardio/combo and kettle bell type exercises.  For this type of workout, I find these shoes to be excellent - they're light, comfortable, and I like the flat profile, especially for squats and lunge type exercises (my feet just feel more planted on the ground with the flat profile).  One issue I've had with traditional cross-trainers is it was always very important for me to buy a shoe with good lateral support - I've found with this flat profile, there isn't much need for lateral support because your foot is so flat and close to the ground, there isn't really anything to "roll" as in a traditional thick cushiony sole - awesome.  For the little amount of running I do in them, I have found that it changes my stride so that I'm running much more on the balls of my feet - some people may or may not like this, and while I'm very happy with these cross trainers I'm not sure if I'd like the Minimus Road for longer runs.

I do not agree with the reviews that report that these shoes do not fit true to size.  I've been wearing NB running shoes and cross training shoes for years and am consistently a size 10 - and these MX20s are no exception.  I will note they are designed to be worn with or without socks, so if you wear thicker socks then maybe you would want to go up a half size.  I've worn these both w/o socks and with very thin athletic socks&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/adidas-Men-s-Climalite-X-II-2-Pack-No-Show-Sock-Medium-Shoe-Size-6-12/dp/B002GWWFUI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">adidas Men's Climalite X II 2-Pack No Show Sock (Medium, Shoe Size 6-12)</a>, and they fit fine and are very comfortable either way.  I think I'm leaning towards preferring to go sock free with these.

While styling wasn't my main concern with these, I think they look great and I like the blue color.  They look like normal athletic shoes, unlike the ridiculous looking Vibram 5-fangers.
