This is a great shoe for women.  Super light, super supportive, you can splay your toes in the toe box.  I feel  energized when I wear these shoes and I wear them a lot.  I wear them for a cardio class a tamara class, walking and a pilates type class and a tromped up and down stairs in London, and climbed volcanoes in Iceland.  I felt very stable.  The shoes are not waterproof, so keep that in mind.  I did size up one half size.  These shoes are made for a woman's foot.  I bought my first pair in my town, when I went back to get another pair, the store said they were not selling here so  they quit carrying them.  The guy did tell me they were selling great across the nation.  Thank you Amazon, for the great price.  I bought two pairs just recently.  To Altra, you have a winner.  Please do not change anything.  I will say my first pair has shoes laces a wee bit too short and the next two I bought has longer laces.
