These feel like interfacing not stretchable mesh like I was expecting. They are shorter than size would indicate and the seam runs over your big toe- very uncomfortable.  I am returning these immediately. They feel like the fabric would fall apart in water and since they don't have any elasticity they fell off my heels when I tried them on. Not usable for water fitness. I hd the white ones, given all the good reviews, I wonder if the other color is something different.
