How long do wallabees take to break in? Had them about a week now and they’re still kinda uncomfortable.

I got them size 9 (my normal size) cause that's what felt best in the shop, but after a week wearing them they feel pretty awkward and uncomfortable, particularly on my left foot. This shocked me, as all I saw online was about how comfortable wallabees are. Not sure if I should tough it out or just sell/return them. Anyone have a similar experience?
