First up I squat raw, not very strong only been training on and off for a short time with a huge break in between due to work commitments. Recently I spent a few hundred and got a pair of adidas adipower weightliftinf shoes for squatting. I usually squat in chucks. I have had problems with knees collapsing in my squat but started to get on top of it. I bought the adipowers as many people mentioned they help with knee valgus.
4 squat session later and it is back worse than ever and I have a horrible sticking point just above parallel during the concentric portion of the squat. The knee valgus is worse when my stance is closer but gets better as I widen my stance (though it is still evident) however the sticking point nearly puts me at a dead stop before I grind through it. Once I pass the sticking point though the bar flies up.
I have tried mini bands around the knees, hip thrusts, wide box squats, pause squats, bulgarians all to build glutes, lowering the weight and building back up, my mobility is excellent, hammies are weak but I have been hittng them with RDLs and even isolation stuff but nothing has worked. I started to get on top of ot when squatting in chucks but since the change to heels it has gotten much worse. The knee valgus is now starting to leave my knees feeling beat and while I have always had crepitus it has become much worse since wearing weightlifting shoes to squat.
Any advice or points I might be missing would help enormously
