Our closed backed clogs offer protection for the back of your feet and keep the clogs from slipping off. It is however important to keep in mind that these are clogs rather than shoes. As you walk, the closed back clog will come up and down slightly on your foot. It is therefore important to leave a bit of room behind your heel so that it can move freely. If your heel cap rubs against the back, you may get blisters so we recommend getting the closed back clogs in a half size bigger than you would for your open backed clogs (for the US and UK closed back clog sizes - this is reflected in the "size tables" option in the menue above).
