| Couldn't have said it better!
I use a tibialis machine by Hammer Strength and find it to be EXCELLENT! But, it was like $450 with shipping... Yikers.
Without spending all of that money, I also like to place my heel on a 25lb. plate with my toes on the floor. Then, put another 25lb plate on your toes (a towel or shirt will comfort those tender toes if you have on thin sneakers). Lift your foot with the weight on your toes as far as you can, and then slowly lower and repeat.
Also, make sure you stretch your tibs out after running by extending your foot all of the way. I like to put the stetched leg behind me and place my foot upside down (toes and the top of the foot on the ground) and stretch by pulling my leg away from my toes. Dunno if this description was good, but it is Friday and my mind is free!
