Every willing customer at the Ultra Running Company is encouraged to have their running form analyzed using our proprietary methods and industry leading technology. It's important to note that shoes generally don't fix running problems, and it's exceedingly rare that a quality neutral shoe will cause them, either. Most specialty running stores continue to focus on concepts like pronation, supination and arch height to justify and recommend stability and motion control shoes. These ideas have been scientifically disproven, and are essentially ineffective when choosing a shoe. Modern technology provides high-tech devices that measure minute differences using lasers and pressure sensors, which look super-impressive and sound really science-y but are actually just designed to sell unnecessary orthotic insoles. Here's the problem: none of this works, and the entire industry knows it. Unfortunately, use of these terms allows for the recommendation of expensive band-aids that provide significant sales margin, so they remain in practice across the country. If you receive a purchase recommendation based on this retail sorcery, we suggest you can do better and as an industry, so can we.
