I have a narrow heel; yet like some roominess in the forefoot.  I also need shoes that don't have a built up heel.  Nike was my initial choice, but then they put "Air" in all their shoes - so much for Nike.  Asics was next (although the heel was a bit wide for me), but they keep raising the heel.  The model from 2 years ago worked; the latest is tough.

These shoes are really light, flexible, move where I want.  They have a snug heel and wider forefoot.  Today I ran a fast 5K in them - and was stunned at how well I did.
