These are light, comfortable sneakers for everyday wear, and I get lots of compliments on them. I typically wear a 6.5 and these are spot on in sizing.

If you find that the round laces keep coming untied, do a Google search for Terry Moore's talk on TED. You're probably just tying them wrong :)

These are fashion sneakers, so they really don't have the kind of padding you'd want for athletics. If you're looking for something to wear to the gym, keep looking.
