Reasonably priced, low around the ankle and full support for my heel to protect against those nasty bone spurs. These are light without being super lightweight, can be used for running OR walking. I currently have a new pair i'm breaking in for some 5ks this spring and I'm using my old pair as hiking sneakers. I've never had a problem with raw spots, calluses or chaffing with these shoes. The white/green combo is awesome for my early runs because they reflect light.
These aren't nearly as narrow as my previous running shoe (Asics GEL_Turbuluent shoes), but they aren't for wide feet, either. I bought this shoe a half-size bigger than my normal size (bought a 9, usually wear 8.5) and they fit like a dream. My heel doesn't slip up and down when I run; while it isn't super tight, my arch is snugly supported and my toes have plenty of room.
