It's all in your mind man. With the pop shoves at least. You just need to jump towards your board. Catch with the front foot and really concentrate on bringing that back foot on. You probably aren't even trying to put both feet on, but not consciously. I had this problem for a long time as well, but with k-flips.
Put enough time in and you'll get it. It's a pain, but there is no secret trick. All it is, is practicing enough.
