Even though this is classified as a running shoe, they are great for those that do circuit training/cross-training.  I am a huge fan of Jillian Michaels and her and K-Swiss have partnered, so I think it's okay to name drop :-) This particular shoe just doesn't have her name on it. I work out exclusively to her DVD's and besides her yoga DVD, a good shoe is needed with the jumping jacks, burpees, mountain climbers, butt kicks, high knees, and every other insane cardio she has you do. Well, she wears them, so I thought why not try them out. My feet stay cradled in place and give a good cushion support and shock absorbtion.  I highly recommend this shoe.  Plus, the color is cute :-)
