my gf must of tried atleast 4 or 5 different pair of salomon and you definately want to buy them a bit bigger. From what she says she tells me that Salomon always fit a bit smaller. She wears a Size 7wmn and she told me that it felt more like a size 6.5-6.75 so it's not a bad idea if you buy 1/2 a size bigger with the salomon but that's just my opinion. She is definately picky when it comes to finding the right kicks for her feet. Whether it's heels, sneakers, or sandles. I would definately recommend a 1/2 a size bigger assuming they pack out but it doesn't seem like it from the material they use.
