As it looks like I’ll be working at home for the foreseeable future, i want some sandals to be able to keep by the door to slip on an off quickly when I pop out. I’ve got some John Lewis vouchers, so thought I might treat myself to some Birkenstocks, are they actually decent quality? What is the sizing like? I’m a size 5 almost everywhere so that’s what I’d normally go for. Just wanted to check as i can’t easily try them on
