I think I could have ordered a 5.5 and they would have fit me better. I have had a few pair of these sneakers. They were always gifted and everyone says to size upbut personally I say size down. I am usually a size ).6-6.5 my daughter is a T=Toddler 8 so Ibought her an 8.5T. She had a pair of gold ones when she was a T7.5 and she grew out of themin weeks. So now she is a T8 and I decided to get a T8.5 and they are very big on her. at least she will have them for awhile . I know for next time now. For me, I definitely could have gotten away with a 5.5 instead of a 6. regardless, these shoes are great! they comfortable, go with just about anything and you can match your family, kids, partner. they’re such a clean and classic look. the bright white and detail make for a classy look. unisex also. These sneakers are my go to. I wouldn’t go running in these sneakers just bc there really isnt any support around the ankle. not at all disappointed a- i love them!
