Five stars for easy purchase and fast shipping.  I believe running shoes may be over rated, but have not had chance to use it yet on long run but so far shoes on short runs have been OK but not great.  I purchased a NB1080 same size 10 months ago and those fit me perfect with excellent cushion and have used them in 3 10K's since the purchase w/o any discomfort.  The NB MR1906 seems snug up front w/o much give. The front-medium-rear sole offers very good support.  The plus is its lightness compared to the 1080.  Unable to give this shoe a fair assessment until I try it in my next 10K.  But I give it a 4 star for now!
