G'day Ben,

These awesome slippers and designed for camp on light weight adventures like multiday hiking, for example.
So they're ideal for in tent or at the hut, or wear around a small camp as opposed to a slipper for use with 4WD/general camping.
Exped have been making these for a while and they're a well loved slipper for adventurers around the world.

G'day Paul,

Check out the size guide, which should pop up when you click on the button next to the size selection menu.
That gives you the US sizing, as well as a centimeter measurement.  We recommend going by the centimeter measurement if you are unsure of your foot size.

Hope that helps.

G'day Rick,

Expeds care instructions are as follows:
To wash Camp Booties and Camp Slippers use a gentle or mild detergent. Select cold water and the delicate cycle on a front-loading machine. Dry in a dryer with no heat or hang dry.
