me: 6'2" at around 200lbs, size 12d shoe. i do not use running shoes for everyday casual wear.
shoes run a little tight around the toes, but only around my right foot (it is slightly larger than the left).  this tightness doesn't really bother me all too much, but i can feel its there.  i typically run on the balls of my feet, and i feel this shoe will be very uncomfortable for the heel striker.  the shoes are indeed light, but they could use a little more cushion in the front of the shoe, because of this, my typical 3 mile run (on concrete) is slightly more painful.  i've only used this pair of shoes once, and will continue to use them, but most likely on a tread mill.  for around the same price, the new balance m890v2 is a far better choice, i currently have 2 new pairs of the new balance m890v2, and was hoping to incorporate the m3090 into my weekly rotation.  link to new balance m890v2 http://www.amazon.com/gp/product/B005BVBRAU/ref=oh_details_o01_s00_i00
