This is my second pair of Salomon shoes. I wear custom orthotics to correct all manner of foot alignment problems. Long, flat feet with weak ankles - not a good combo! These shoes do run large. I'm usually 9, but got size 8 and they're bang on. They are ultra comfy and supportive, great grip, stable, and brilliant for day-long trail walking that I do. As with all higher-end salomon footwear I've come across, your feet just don't rock or feel like they're going to roll. Ever. They support orthotics brilliantly (unlike other 'softer' shoes). I love them. They even look good! They also have a good arch support fit without orthotics - something rarely found. A mark of a company that knows what feet are actually like.
