I went for a shoe fitting appointment today at running store. The technology has come so far ahead now! Several years back the experts would make you walk, run and generally do a few things to really understand and do gait analysis. Now? You just stand on a board that automatically scans your feet & arches. Then you walk on a sensor board few times to do additional weight analysis. All of it directly uploaded into an awesome 3d rendering view of your shoe size, arches, pressure and weight points, sent over email to you. Tech has come so far! It was an awesome experience.
