Some of the new cross-trainer shoes look more like a casual shoe than something you can work out in. I recently saw an ad that had some cross-trainers for sale and I was amazed at all the choices.
The last pair of cross-trainer shoes I bought was about four years ago. I don't wear them very often so haven't paid much attention to the styles.
I like some of the newer styles that use a mesh material in their shoes. These look like they would be great to wear in hot weather and give your feet room to breathe.
