Would these be ok for light hiking?

Are these listed in mens sizes unless otherwise notated? I am wondering if 6 means 6 mens aka 7.5/8 women?

I wear a womens size 7.5 running shoe, 7 regular shoe and have a narrow foot. I see they only have sizes 6 and 7, no half so which do you recommend?

Do they have inner soles? If yes are they laid in loose, glued in, or sewn in?
