Part of this, I'm not sure how relevant it is, but I have biggish feet (Size 13 US). Like without shoes I can easily kick it 44+metres (43yards) but with shoes on, the best I seem to do is roughly 37metres (40yards). And this is just when the ball is still (eg a goalkick sort of thing). Also with shoes on I struggle to get 'under' the ball as I kick it, esp at full power. Anyway anybody know how I can improve that? I've got relatively strong legs, so I don't think it's merely a weakness thing.
