I can recommend Saucony as a brand, but not necessarily as shoes for you. That's the part that only you could determine yourself. Saucony has a good reputation for making fast shoes - especially the low-drop lightweight types. This includes road, trail, track and XC. The one negative about Saucony (but many other brands are also guilty of this) is that they like to tinker with their designs, so the fit, feel and quality of a shoe often change from model to model. They do tend to be narrow so might want to try half a size up. They have wider sizes in some of the ranges but I haven't seen those in SA. Half sizing could help with this but be careful to not leave too much space up front - you still want the forefoot area to flex in the correct areas. Specialist shops (read not Sportsmans') could help you with this. Coming from the Ghosts, you can try something like Saucony's Triumph (expensive!) or Ride series.
