I'd be very skeptical of any analysis that takes one minute at a shoe shop. I'd wager those machines are there to anchor, so to speak, a buying decision.
Too much running before the body gets strong enough to handle it, along with hard surfaces are more likely the culprit behind shin splints than poor choice of shoe.
You don’t need a machine you need someone to observe your feet as you run. Then based on your roll, buy shoes that support your feet. This is not rocket science, you need new running shoes every year or two. Protect your shins, get proper shoes, if it’s a minute to analyze on a treadmill (“machine”) then take the minute. If you have a friend, have them take a minute..
