Mushy loose heel. tight in all the wrong places - Altra Arrows HIIT XT Road Running Shoe - Women's

I have been wearing Altra shoes for a year or two now. They are my favorite for trail running (Lone Peak 3.5). I do have a wide foot and love lots of toe room. I got these shoes to wear for CrossFit. They looked promising and I could not wait to get a pair. These arrived today so, to be fair, there has been no break-in time at all. However the main things I do not like about these shoes is not a break-in issue. The thing I dislike the most is the heel is WAY over padded and loose. My heel actually comes up from the shoe when I walk. This is a serious problem for me when doing box jumps. That could be dangerous. And... yes I do have them laces using the loop into the extra hole to lock down the heel. It is not enough. The next thing I dislike is that these shoes are not as roomy as other Altra shoes. In fact they are downright tight from the toe-ball all the way up the the top of the arch of the foot. The shoe feels too tight everywhere except the heel. The anatomy of this shoe is just wrong for me. I do like the sole but it just doesn't work with the fit of the shoe. I have seen fantastic reviews for this shoe and I am amazed. This is a no go for me.
