The reason is that although the courts of the various Commonwealth nations are often influenced by each other's rulings, American courts rarely follow post-Revolution Commonwealth rulings unless there is no American ruling on point, the facts and law at issue are nearly identical, and the reasoning is strongly persuasive.

Those designed for grass pitches have studs on the outsole to aid grip. From simple and humble beginnings football boots have come a long way and today find themselves subject to much research, development, sponsorship and marketing at the heart of a multi-national global industry. Modern ``boots'' are not truly boots in that they do not cover the ankle - like most other types of specialist sports footwear, their basic design and appearance has converged with that of sneakers since the 1960s.
 Question: are football boots and soccer boots the same Context: The high-resolution, digital cinema grade video projector alternately projects right-eye frames and left-eye frames, switching between them 144 times per second. The projector is either a Texas Instruments Digital Light Processing device or Sony's reflective LCOS (liquid crystal on silicon). A push-pull electro-optical liquid crystal modulator called a ZScreen is placed immediately in front of the projector lens to alternately polarize each frame. It circularly polarizes the frames clockwise for the right eye and counter-clockwise for the left eye. The audience wears circularly polarized glasses that have oppositely polarized lenses that ensures each eye sees only its designated frame. In RealD Cinema, each frame is projected three times to reduce flicker, a system called triple flash. The source video is usually produced at 24 frames per second per eye (total 48 frames/s), which may result in subtle ghosting and stuttering on horizontal camera movements. A silver screen is used to maintain the light polarization upon reflection and to reduce reflection loss to counter some of the significant light loss due to polarization filter absorption. The result is a 3D picture that seems to extend behind and in front of the screen itself.
