I have personally found these shoes an excellent quality.  I have slightly wide feet and need the extra room in the front of the shoe.  I walk a dog a lot and do some pretty intense exercising on these shoes.

I bought 2 pairs of the black color.  One pair is worn to work and the other pair is worn to the gym.  I can change them in the car on the way to the gym.

I often have trouble finding athletic shoes with a low back on them.  These are perfect.  The back of my ankle is not rubbed sore.
