I have a wide foot and high in-step(thicker), plus a large ankle-leg. This boot accommodated my needs. It was a little difficult pulling on for the reasons already stated, but once on, it was very comfortable for me. I would buy this brand again, if I can get similiar features. For me, a zipper  is always better as far as getting into a boot, if they still leave a wider shaft.  I pulled hard on the pull tabs to get past the stuck point, and the inside ripped. It was more for style than strength and practical use. So I quit yanking on that piece.
