My wife really loves these workout sneakers from Zumba.  They are light, highly breathable, and feature enough cushioning so that her feet don't hurt while she's wearing them.  The "tongue" is actually built into the shoe and my wife likes this feature.  She also appreciates the compression and "sock-like" feel of the upper part of the shoe.

My wife also likes the look and color of these shoes.  The bright lime green coloring is fun and the holographic heel is very cool according to my kids.

Keep in mind that these shoes are intended for use during Zumba classes, so the sole of these shoes is intentionally less slip resistant than standard sneakers.

These shoes are fun and functional, and that's an excellent combination.  Five stars.
