I have a low volume foot.  Not a narrow foot - low volume.  I am slender (5'9" @ 135lbs) and my foot is also.  Finding a shoe that fits well without tightening the laces to the max is a challenge.  I tried on about 10 different shoes and these fit PERFECT.  So, if you have a low volume foot, low instep, low to medium arch - give these shoes a try.  I have a neutral gate so these work fine for that.  I also found that it fit true to size; the Nimbus 12 runs a little small.  Lastly, I have a bad knee so cushioning was important.  I found, for cushioning, of all the shoes I tried these were as good as any other, including the Asics Nimbus 12 & better than the Nike Vomero 5.  However, the Asics Cumulus 12 is probably the best cushioning shoe out there.  Also, if your foot is as described above, or if you have a narrow heel, try Sauconys, they should fit you well.  If you have a larger volume foot, try the New Balance 993.
  Lastly, these are  not a trail shoe, but hard pavement shoes.  They pick up small stones easily and have distinct road feel, which may not be welcomed on a rough serface.  Ah, yes, for what it's worth - these were Runner's World "Editor's Choice" for 2010.
