I've worn these shoes to work out FOREVER and they are great--durable, comfortable, and no rubbing my feet even with frequent, high impact exercise. I've been a Turbo Kick ([...]) enthusiast for years, and since 2009 I've been an instructor and I can tell you firsthand these comfy shoes take a beating. They run true to normal size.

Note: The white and pink version of these sneaks irritate my feet and crush my toes, even in the same size. :(
