I remember when I was a few months into barbells and I was trying to figure out my squat. I asked a lot of people in the gym for advice, and everyone was able to find something they thought looked atrocious. So I’d try their suggestions, like trying to keep my shins perfectly vertical. Or looking straight up, because everyone knows you’re supposed to look up when you squat. Plates under the heels were suggested, which did not improve anything and felt like crap to me. Oh you gotta get chuck taylor shoes too, because they fucking read it somewhere online probably.
Eventually I decided to just wear the goddamn toe shoes that were comfortable* to me, put the bar low where it was comfortable* for me, use the thumbless grip that was comfortable* for me not worry about what my shins and ankles looked like. Throw in a good dose of consistency and a conscious effort to improve tightness and I was doing pretty good for an un-coached gym rat/hobby lifter.
That’s when my squat started to take off. If it feels good, you’re good. Oh, and it turns out that most of the people who gave me advice are really pretty shitty squatters. I just didn’t know enough at the time to sniff out their bullshit.
*comfortable in this sense means no acute pain during or while recovering from squats. There’s really nothing comfortable about squatting if you’re doing it right. That’s what I mean when I say “feels good”.
