Semi-related: I did the gait analysis thing when I started seriously training for a half marathon. The guy showed me the video and reached the conclusion that, since I run with my knees flexed inwards (true) I needed a certain shoe that would "stabilize" my feet and push my knees outwards. It took me several years and several pieces of orthopedic equipment to recover from the damage those shoes did to me. Do not trust salesmen with medical advice.

Can I ask how the shoes created actual orthopedic damage? (I totally understand how hard injury and recovery are, so not flaming. I destroyed my hip cartilage while a happy runner and triathlete, so I know about injuries, recovery and letting go of something I adored and that defined me.) Shoes * body * mileage = impact, where body gives signs of damage being done and is also the one to work on via technique and strength if something is not going well in your posture. I see the 'duck run' (knee buckling inside, feet moving outside to correct for the loss of height) all the time and would think that something that mostly is related to underdeveloped muscles around the knee.

  The explanation I got from my doctor was that one shouldn't fix posture problems by raising the inner part of the insoles a random amount because all that achieves is making you run "weird", putting pressure in the wrong part of the articulation and damaging the ligaments that keep the knee in place. The actual solution involved muscle development exercises, ripping out the insoles of those shoes to achieve a flat base and replacing them with custom-made ones, knee pads with metallic inserts, and a two-year training plan.

    Conventional wisdom among running coaches and orthopedists these days is that the most important thing is to run comfortably, and that just because something looks "weird" doesn't necessarily mean it's bad or wrong. Yes, it may be inefficient, but it probably isn't hurting the runner, either.

Just as a counterpoint to this. I was having ankle pain and had one of these gait analyses and also had inward pointing knees and got some shoes to correct it - and it helped loads! Much less knee pain and my ankle feels lessy achey too. So don’t trust all sales people - especially if feel fine already. But if you have an issue it really can help.

For me I didn't realize that my feet had actually grown and I was cramming my feet into the old sized shoes (and kept buying the old size too). Took years to figure that one out :-/

  Yeah it’s amazing - but I think feet don’t grow on adults, they get flatter over time and therefore longer/wider footprint.

    I think you're right - this was also during Covid where I was home and barefoot alot more. The effect is the same though which is that I need bigger shoes now and just that simple change solved alot of pain (also getting jeans that fit right).
