Zoris are thong-type sandals where the straps are assembled to the sole by plugging into holes — a specific construction method. Sandals with straps attached by stitching, adhesive, or other means do not qualify as zoris and are classified under 640299 or another appropriate subheading depending on ankle coverage.

Yes. Classification is determined by the material of the outer sole and the upper's outer surface, not by interior lining materials. A shoe with a rubber or plastic outer sole and a rubber or plastic upper — even with a textile lining — classifies under 6402, not under the heading for textile-upper footwear.
