“…Open-toed shoes, particularly sandals (also called "chappals") and flip-flops (also called "slippers," "Hawaii chappals," "Hawaii slippers," and "sandals with forking"), were the most common footwear in nearly all (n=20) of the included studies, in clear contrast with the recommendations of international guidelines. 15 The popularity of sandals and flip-flops was largely consistent across samples from different world regions, with lower 41,43,56 and higher 24,58 education levels, lower 43,44,46,62 and higher 55,58 income levels, lower 47,50,57-60 and higher 24,41,46,[52][53][54]56,61,62,64 DFU risk levels, and from more 24,44,46,48,49,54,56,58 or less 41,49,50,52,55,59,60 urban locations, though not all articles thoroughly reported all of these demographic characteristics.…”
