I love these shoes and wore them all summer.  They're very hardy and clearly well-constructed, and take awhile to show signs of wear (except for the superfluous bit of soft rubber at the toe, which wore off VERY quickly).  Traction is great.  The insole is nicely textured, and easily removable and washable with baking soda.  There's even somewhat more arch support compared to most other flats.  Because of the material, it'll shrink a little bit after being wet, but stretches back to comfiness quickly.

I usually wear a perfect women's size 7, but got a 6.5, which was a little tight but the hemp material stretches out to perfection in just a few wears.  This is confusing since some other reviews say they run a half size too small... I'd recommend getting your true size.
