How it fits

REEF sandals and flip-flops come in US sizes. Most of the adult styles we carry come in whole sizes.

Your foot should sit fully on the footbed, with your heel and toes not hanging over the edge.

Between sizes

Between sizes? Size up if you wear thick socks or orthotics, or you're on your feet all day. Choose the smaller size if you like a snug fit.

Some of our REEF kids’ styles are labeled in paired sizes, like 5–6; a paired size covers both sizes on the chart. Kids’ sizes start over at 1 after 13.

Growing room (kids)

How much room? About a thumb’s width at the toe — roughly ½ inch (1 to 1.5 cm) between the longest toe and the end of the shoe.

Thumb test: with your child standing, press the tip of your thumb down at the front of the shoe. You should be able to press down without hitting a toe.

Time for a bigger size if toes are pressed against the front, the shoe leaves deep marks or blisters, or your child says their feet hurt. Too big if their heel lifts out when walking, or they trip or drag their feet.

How to measure

Measure at the end of the day, when feet are at their largest.
Stand on a sheet of paper and mark the tip of your big toe and the outermost part of your heel.
Measure the distance between the marks and compare it to the chart.
Measure both feet and use the longer one.
