There are three primary causes of thongs hurting your toes – (1) the material of the thong that comes into contact with your toe, (2) the thickness of the thong, and (3) the sensitivity of your skin. We use microsuede as upper lining/thong material in most designs and always make sure to optimize the thong thickness during design, development, and production. But while the possibility of our thong hurting your toes is lower than thongs made by other brands, we can’t guarantee that our thong would not hurt your toes, especially if you have very sensitive skin. So if you want to be completely assured that the footwear you purchase from us would not hurt your toes, you might want to consider our slip-on designs instead.
