I have Never had a problem wearing boys size 6 and for some reason I have been trying to find for the longest time boys size 6 and purchase multiple pairs and they just don't fit the same way the original pair that Ive purchased fit!! It is super frustrating because I have been able to replace my original pair actually that my boyfriend bought for me I am normally a size 7 7 1/2 depending on the shoe and this is just driving me absolutely insane they are actually a little bit snug in the top of the sandal.
