You can measure your foot by backing it up against a wall barefoot and measure out. Generally for summer sock thickness and to ensure toes aren't rubbing on front, you want a boot that is your foot length plus ~1/2-5/8"
Note, depending on the size, some have laces that run short, so when lacing, it works to skip some of the eyelets at the mid section (see second picture).
