New Shoes

I have done about 15 miles in these shoes so far and I haven’t decided if I really like them or not.  I have never owned a pair of women's running shoes because of my very wide feet but I thought I give these a try.  They are a size 12 so the length is about right.  I am concerned if I can run the half marathon in them.  I am used to having room in the toes rather than them fitting just right.
