Slim calves - how?

Anyone out there know how to slim down calves???  I've always had big arms and calves.  I do pilates, yoga, and ****il recently due to the instructor being fired) turbo kick.  I occasionaly weight lift.  I *hate* the treadmill, elliptical, and bike.  If I'm going to do cardio, I want to be in a class. Thanks in advance!

Not a fan of walking, unless it's shoe shopping!  But to walk for exercise, no, not so much.  I'd rather get my cardio in a class.  My legs are a mix of muscle and flab (just 5 months post-op -82lbs) - I won't even talk about my arms.  Fatty batwings, you can see the line of muscle!
