These Birkenstock Arizona Shearling Sandals ($160) are the shoes that made me fall in love with Birkenstocks. They're my go-to house shoes because they are super comfortable and keep your feet cosy without overheating. They've also got good traction on the sole, so I'm not slipping and sliding through my house as I wear them. They come in lots of different colours, and once you try them, you'll never want to take them off.
