Pronation-based shoe fitting has not held up well in research, which changes how this decision should be made.
Verdict
Choose on comfort, not on a pronation reading. The long-standing practice of matching shoes to foot roll has repeatedly failed to show an injury benefit in controlled studies, and the most consistent predictor of both comfort and lower injury rates is simply the shoe that feels best to run in. Try a neutral shoe first, and try a stability shoe if the neutral one feels unstable.
For two decades, running shops assessed pronation and sold shoes accordingly. Several controlled trials since, including large military cohort studies, have failed to find that prescribing shoes by foot type reduces injuries, and some found no difference at all. That is not the same as saying stability shoes are useless; plenty of runners genuinely prefer them. It means the prescription model was doing less than it claimed.
What has held up better is comfort. Studies of shoe comfort and injury have generally found that runners allowed to select the most comfortable option get on better than those assigned a shoe by category.

You have no history of injury tied to a specific shoe, or the neutral shoe simply feels better. Neutral shoes are lighter, less structured and are what most runners get along with. Buy on fit and comfort: enough room at the toe, no pressure points, and no sensation of fighting the shoe. Try them at the end of the day when your feet are largest.

A neutral shoe feels unstable to you, you have had good experiences in stability shoes before, or a clinician treating a specific problem has suggested one. Modern stability shoes use broader midsoles and guide rails rather than the hard medial posts of the past, so they feel far less corrective than the category name implies. If it feels better, it is the right shoe, and that is a sufficient reason.

Recurrent running injuries are far more often a training load problem than a shoe problem. Sudden increases in weekly mileage or intensity, insufficient recovery and a history of previous injury are the factors that show up most consistently in the research. If you are injured repeatedly, a physiotherapist or sports doctor looking at your training and your movement is a better investment than another shoe.
Not necessarily. Controlled studies, including large military trials, have generally failed to show that prescribing shoes by foot type reduces injuries. Some degree of pronation is normal and functional. Choose the shoe that feels most comfortable to run in, which is the selection method with better support behind it.
Run in them. Comfort is the most reliable guide, and it is a better predictor than a wet footprint test or a treadmill gait video. Most specialist running shops will let you run in shoes before buying. Fit at the end of the day, with the socks you actually run in, and leave a thumb's width at the toe.
The heavily corrective motion control category has largely been replaced by softer approaches such as guide rails and broader midsoles, which nudge rather than block. That shift followed the research failing to support the older, more prescriptive model.
Commonly 300 to 500 miles, though it depends on your weight, your gait, the surface and the shoe. The more useful signals are the midsole feeling flat and dead, new aches appearing on familiar runs, and visible compression creasing along the foam.
