Footer height is much higher than regular

No, there is no height set, it’s simply set by the elements in that section of the page — see this CSS – likely the padding:

#footer .wrap {
    font-size: 11px;
    margin: 0 auto;
    overflow: hidden;
    padding: 16px 0 25px;
    text-transform: none;
    width: 960px;
}

But be aware that you should not make changes to theme files — rather use a Child Theme or custom CSS option or plug-in.
