I have several pairs of Ryka shoes. I like them because the toe box is large and the heel is a bit narrow. I haven't had a problem with "break-in" time with Ryka's either. With other "tennis" shoes, my toes feel so squished that sometimes they fall asleep. I also have trouble with the heel of the shoe slipping up and down on my foot with other brands. In this particular Ryka shoe, the toe box seems a bit larger than other Ryka's I've had. The shoe is also VERY light weight. The only thing I would change about this shoe is the heel--there is a piece that comes a bit higher on the back of the heel than the shoe itself; I would have omitted that "extra" piece.
