I ordered on 11.15 and received on 12.16. Almost a month to the day. I’m gonna say these run true to size because I wear an 8 and to be on the safe side I ordered an 8.5. And they’re about a half size too big. But they’re definitely do-able. They have a very strong chemical smell which I smelled it before I took them out the box. They came in plastic baggies. I’ll let them air out AND IT WILL BE FINE.
