So just an update, I got my tieks in Cardinal Red and as much as I wanted to love it, it's just not for me.
I almost always wear a size 7 with rare instances that I had to go down to 6.5 but never a 7.5. The 7 tieks that I got when i tried it, my toes are curled but sliding out at the back and wide on the sides. I am pretty sure that if I go get a size 8, it will be big since the 7 is already wide on the sides.
I'm so sad because I had been wanting all the other colors already and the leather was just so soft.
