These make a huge difference for squatting movements. I was using rubber wedges to elevate my heels which makes it a bit awkward when getting into place for squats. These really help with ankle mobility and my feet feel glued to the floor. I have normal width feet and they are snug so wide feet may be an issue. I normally wear a size 11 and most reviews said to size up and I am glad I went to 11.5 because the fit was perfect but still snug which is what you want foe support. I only use these on leg days because I feel like a Clydesdale walking around in them.
