this shoe is snug and lightweight.  I don't like a lot of room when I am working out, so I was pleased to find that this shoe is such a foot-hugger.  the toe box is a bit funny in its shape and I need to get used to it as it is unlike my Asics squash shoes where you can feel the contact of the ball of your foot on the floor.  With this shoe there is no such contact without imposing one's weight.
