Allbirds Tree Flyer white and grey

LOVE my Allbirds. My first ones were a 6 and was loose, thought a 5 would work but it’s a bit too snug with so much heel cushion. I am normally a 5.5 and thought these might run big but they are pretty true to size. And a bit narrow but could still wear socks with them. Worn a few times to try and make it work. Washed them but please note the slight imperfections on the heels and midsole.
