Couple of things going on here that I am seeing that may be increasing your risk of edge catches:
1) You are riding with very low edge angles consistently rather than tilting the board higher onto its edge. This is a result of very static legs. Notice how you are riding pretty tall all of the time with nor flexion and extension? Work on flexion and extension to get higher edge angles. If you are riding solidly on an edge, it is impossible to catch an edge. For now, simply focus on getting really low (bend ankles and knees) just before the edge change, then once you start the new turn, slowly extend through the turn.
2) While your riding overall is looking very solid, you are pushing the back foot around still like a rudder. This is most noticeable in your heelside turns. The board is pivoting way more than twisting and tilting. This is also a result of very static riding as mentioned in (1)
3)Your stance width looks too wide in that it appears to be impeding your range of movement. Ideal stance width is a "sweet spot"; too narrow and it lessens your range of movement and too wide also lessens range of movement. To dial in your ideal stance width, do the following:
Without the board strapped on, place your feet about shoulder width apart and then squat down as low as you can go without pain and I mean get really low. You will have to adjust your feet to accommodate this. Rise up and squat low several time and move the feet in and out to find the spot that allows you the most range of movement with the most comfort. Measure the distance between the center of each foot. This will be your ideal stance width.....:thumbsup:
Other than the above, just start getting more dynamic overall and use twist and tilt to steer the board, not pivot and start working with this constant getting low before the turn and rising up through the turn and you should not only reduce your edge catches but feel a lot smoother in all of your riding. Once you get this dialed in, it is time to talk about up and down unweighting for your edge changes...
