Gurkees Rope Sandals come in half-to-whole sizes.  So a size 8 Gurkee will actually be size 7.5-8.

If you wear a 10 in tennis shoes, you would most likely take a 10 in Gurkees. If you wear a half size, move up to the next whole size. If you are in doubt, it is better to order the next size up.

If your Gurkees don't fit, you can always exchange them for a different size!
