As with all Salomon shoes I had to order a half size smaller than my usual size in other brands.  Even then I have ample room for thick socks.  These shoes served me well on an 8 day excursion through rain and rocky terrain.  Grips great to wet rocks, comfortable with sturdy ankle support.  Wear socks that go above the shoes, or you will get some discomfort/blisters from the back top rubbing.  Also, be careful- as with any shoes with hooks for laces, they can catch on the lace of the opposite foot and make you trip, which is a big no no in precarious terrain.  Tie your shoelaces so there are no long loops that hang loose and catch onto the hooks of the opposite shoe.  Otherwise good solid waterproof Salomons.
