I've found that Salomons run a tad small. I wear either 10's or 10.5's in all shoes, but a 10.5 in Salomons works best for me. For you, I'd say the 9.5 would be a good choice.
I think this is a short to medium distance model because they don't have any sort of pronation control or stability plate such as in XT or XA models. They have excellent cushion and forward momentum, though, so I dont think they would be a problem on longer runs.
