I started working out and my ankles were killing me.  Kill. Ing. Me.  I went to the doctor and he couldn't figure out what, exactly, was wrong, but he told me I was majorly pronating.  I did a little bit of research and settled on this shoe (found it cheapest here on Amazon).

I've used these shoes for several weeks now, and I have absolutely no ankle pain whatsoever.  I firmly believe it's because of this shoe and the quality of support it offers.  I do circuit training in my living room (hard wood floor) so I haven't tested these outside.

The shoes aren't very "stylish" I guess, but that doesn't bother me at all.  They're certainly not ugly, just functional.  Super pleased with these, and when I need another pair of athletic shoes I'm definitely getting more New Balance.
