"I’ve been wearing Birkenstock clogs for a couple years and can’t overstate how much more comfortable these are. They do stretch out a little and they run big - I’m normally a 10 and had to size down to a 9 - but the footbed is super supportive and the upper hugs your foot in such a comforting way. I’ve been living in these since I got them."
