They help me get a bit lower, while also providing a really steady surface. Since your squats are already deep, maybe they won't do as much.Interesting. JD said that he didn't think that they'd help much for raw squats with my stance, but recommended some Oly shoes for catching in those lifts.
But when I said "better angles" I meant mostly for the front squats/overhead squats, so yeah, it should help with catching the lifts.
