i have own this product for almost a week now . at first , the sandal strap -lrb- where the top of you foot make contact with the strap -rrb- be extremely tight , and i could barely fit my foot in they . even the thong area become sore even though i wear sandal almost every day . this be extremely uncomfortable and quite painful . i read that these sandal take a bit of time to break in until they feel comfortable . still , i be unsure , because it be fit so uncomfortably tight . after battle through two day of break they in , they finally fit comfortably , and i be glad i stick with they . everyone i know who own a pair of rainbow highly recommend it because of how long they last . i hope to wear these until they completely wear out .
