Why don't running shoe manufacturers make multiple shoes within a line that fit identically but have different levels of pronation control?
For example, as I've gotten older I find it increasingly difficult to find comfortable running shoes, and the Saucony Progrid Omni is the only one I can find that fits like a glove. But the problem is that I hate the posting/anti-pronation control. It may be considered moderate posting, but it's still uncomfortable (and becomes even more so as the softer midsole material breaks in and/or breaks down). In this example, why can't Saucony make the exact same shoe with no posting?
