Thanks for providing the links!
Upon checking into your website, I figured the alignment of components is collapsing because of using sidebar on your product page. I’d recommend disabling the sidebar will give you proper alignment as per shown here (see: http://prntscr.com/9zhs2q). In order to disable sidebar; please go to your product page and select ‘no-sidebar’ from under page options.
I’ve also noticed your header is chopped off, in order to fix that; please go to your Appearance -> Theme Options -> Header, and increase the ‘padding bottom’ up to 90px, as per shown here (see: http://prntscr.com/9zhvgg).
Hope this helps.
