Minnows are made from plush, soft, stretchy neoprene. They’re meant to fit snug so that they keep out the water and the sand, but not so snug that they don’t feel like walking on a pillow. They have some stretch, like wetsuits. If in doubt, we suggest that you go up a size.
You can order your Minnows according to your child’s regular shoe size (or up a size if their toes don’t have a lot of room in their current shoes). Or, for more accurate sizing you can measure your little one’s foot according to the below instructions.
