Sending back shoes (shoes for crews)

Does anyone know if I’m able to send back shoes even after wearing them for one shift? Figured I’d ask before going in tomorrow. I got my shoes & they’re seriously horrible. I got my normal size & they’re so small on me (this particular shoe didn’t say to size up or down). I wore them for one shift and it killed me. I didn’t know they barely had support and by the end of my 5 hour shift, I had to walk on my tippie toes & my back was killing! I got dr scholls inserts too but because of the shoe already being small, i legit can’t get my feet in them now lol. There was prob no need for this rant as I was just looking for an answer here but I just had to rant about them lol.
