Hi. I wear Salomon XR Mission for running in the woods and on rough grassland. The are very comfortable. I have just bought some Salomon XA pro 3D GTX. (dramatically reduced) I have only tried them on in the house, but they feel a little narrow across the middle of the toe box, and quite stiff. I have read elsewhere that they do soften up and become more flexible with a little wear. Does anyone here wear these for trail running and if so would you agree that they take a bit more wearing in than a road running shoe? I'm wondering whether to keep them .
