Okay, so AirMax are great shoes, and are good for runners who "under pronate" or "supinate"
This is the way your foot lands and rolls when you run .. your "gait"
Runners will pronate, under pronate (supinate) or be neutral.
Different shoes have different soft and hard areas in the soles. Some runners need high arch support, or a firm support, or soft cushioning.
Here's what you should do ...
I don't know where you live, but go on Google, and find a sports shop which offers treadmill assessment, or gait analysis.
Go in with your shoes, and ask them to do a gait analysis.
Is your shoes are not right for your running roll, change them, or you will never stop the pain.
You don't have to pay any extra ... you just have to get the right shoes.
If they are the right shoes for you ... how old are they? The support does go.
I change my shoes every few hundred miles ... about every 6 months or so. After that, they are still fine for casual wear, but not for running.
Next thing ... buy some running socks. These have a band of support round the middle of the foot. They feel weird out of your shoe, but make a big difference with your shoes on. If your foot os not held properly in the shoe, your lower leg will make continual, un-noticeable adjustments to compensate - the "power plate" principle, and that will make your lower legs hurt.
But first thing ... check out those shoes.
