Red Havainas flip flops from Brazil with flag

Cute pair of Havaianas flip flops in a slightly burnished (not cherry) red. 38-39. USA 6, Euro 39.0. None of those sizes match up in my opinion. They were my moms and she is a 7.5 women’s. Mainly heel wear-lots of life left. Best color match is the one on my son, second photo. Yellow, green and cream stripes on side. Brazil flag symbol as they were purchased while we were in Brazil.
