I asked my physical therapist what walk:run shoe I should get, and she noticed I was a flat footed over pronator and should limit my purchase accordingly.  I narrowed my choices down to this Brooks and NB-933, and settled for the Brooks because it was cheaper, less bulky and available in all black, which may be helpful should you wear these at work.  I took my Brooks for a 3 mile 1 hour treadmill walk, and my feet felt noticeably less fatigued even hours after my workout.  You will feel the arch support on the inner side of your foot, but the slope to the center of your foot is gradual enough as not to bite into it like I suffered while trying a 3 mile walk in Asics Evolution or Foundation shoes.
These Brooks have mesh vents along the sides of the shoe like Asics and Nike runners, so they may not be good for running in the wet and cold or a muddy trail, so I may get more rugged and sealed NB-933 for that application should I find them 50% at an end of season sale.  Brooks have these odd flaps beside most lace holes that are designed to hold the lace so tension does not travel up and down your foot.  This may take some getting used to if you are used to tightening your laces at the top and hope that tension will pull the lace tense all the way down your foot.  So basically you have to pluck the laces starting from the bottom and working your way up in order to get a really excellent firm fit - sort of like lacing ice skates.
A few tips for you online sneakers shoppers:  If you normally buy a 10 medium shoe, either get 10.5 medium or 10.0 wide on a running shoe.  If you only want a shoe to fast or power walk in, get a runner anyway, as they are constructed for similar duties while the runners are of more durable materials so they last longer. If you want something to walk short distances and stand around a lot in, then a Walking shoe will help keep your foot planted flatter so it will feel more comfortable long hours on your feet than a runner.  If you want to walk:run on a trail, not on asphalt, then you really should be looking at trail or hiking shoes, or make sure to get rugged runner like&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/New-Balance-Men-s-MR993-Running-Shoe/dp/B001792H5O/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">New Balance Men's MR993 Running Shoe</a>.  and finally, if you are not aware of your level of pronation (severe over neutral under) - you really should find out.  some sneaker specialty shops can evaluate your level of pronation to help you narrow down your search for the shoe that not only fits best, but is healthier for you to walk:run in.
