I used to get shin splints when I power walked too. Then I attended a running clinic at a gym where they analyzed my stride and help me make improvements. It made a big difference. Also, make sure you are wearing good shoes.
Tight and painful sounds to me like underdeveloped foot dorsiflexors (tibialis anterior, extensor hallicus longus, and pronator tertius to fight against the TA). Those muscles just lift your foot up when you take a step. They tend not to work so hard unless you start walking really fast and most people don't really strengthen them unless they have been power walking for a while.
Back in college, i was doing an army physical fitness test and had to speed walk it due to a back injury. My legs were dying at the end. It would have been much easier to run.
However, if the inside part of your lower leg is tender to touch and it hurts to hop on one foot, then it may be shin splints, or medial tibial stress syndrome. In that case, it's rest then working at it more slowly after fixing your running/walking form.

I used to get shin splints when I walked fast, but not when I ran. I asked a running friend about it, and he suggested that my stride might be too long when I walked fast. I paid close attention and made sure to shorten my stride the next time I walked, and sure enough, no pain! So I'd say the first thing to check would be your stride length.

I got t his really fantastic email from Runner's World the other day that talks about shin pain, the different kinds, how to treat it, and how to prevent it!
