hello... I purchased a pair of black flat netted material bobs some months ago... I love the comfort of the shoe but when worn I noticed my colored toe nail polish would have a black stain on the color . I know that's from the dye of the shoe being black . I have many black shoes other brands never have I had it on my nail polish so it is disappointing that occurs I did go back to the store later and discussed it with someone there she was not sure why but was willing to exchange but didn't have my size ** . Then covid happen stores closed . so I would like to see if this has been an issue or just my shoe .I would like a replacement thank you sincerely, Cecilia Kafaty
