Jordan 11 sizing LJR vs Y3

hey guys did anyone noticed that LJR J11s fits slightly bigger than retail? I tried retail J11s in a size 11 and they were kinda tight to me, while with LJR in a size 11 I have a lot of heel slipping.

someone knows if there's a difference between Y3 and LJR in terms of sizing for the J11? like if Y3 fits slightly tighter like retail
