I need a 1/2 size larger

I usually wear a 7. 5, but my feet have changed after 3 kids so I get stuck when ordering shoes. I went safe and went with the 8. I prob could’ve got a 7. 5 though. I was walking in the mall with these and my feet were hurting! Not terrible but I couldn’t wait to get them off. I wondered if I had too much room and that cause them to rub but the sides of my feet/baby toes were hurting after a while of wearing them. The look is 5 stars but the comfort I’ll rest @ a 3.
