The Salomon Women's XT Wings running shoe is a solid, long-distance shoe.  Also great for those shorter runs, but definitely my go to shoe for distance (10K to 1/2 marathon).  The shoe is a bit stiffer than many running shoes, so there is a necessary break-in period, which I accomplished with shorter runs.  Afterwards, it is the only running shoe I am using on the distance runs because of its solid support and stability.
