Please note: Use of the gaiter's lace hook is necessary for proper fit, and should be attached to shoelaces at least 7.5 inches forward from heel of shoe. Using a ruler, measure your shoes from the heel area straight forward to the lace area, like in the illustration below. If you've still got laces at 7.5" on the ruler, you're all set! Now simply refer to the above sizing chart to determine which size LevaGaiter you need.

Between sizes? Consider going with a LARGE unless your feet/shoes are narrow (B width) or otherwise low-volume.
