Whether its first thing in the morning, making coffee before the sun, or sinking into them after leaving street-shoes in the vestibule after a full day, these are so much more than slippers. They're built in the same way Olukai makes the rest of their shoes: rugged yet relaxed. The plush-yet-firm woolen footbed lets your feet breathe, with socks or without. The shearling upper is the icing on the cake, it just welcomes you home every time you put your feet inside. The only downside to these is self-imposed: they don't get to go outside. Pairs perfectly with a Mr. Rogers cardigan and a rainy afternoon.
I wear a 43.5 and the 44 fits with just the right amount of room to relax.
