Bobux shoes are designed to include a little extra ‘wiggle room’, so sizing might seem larger than other brands. If your child measures at the beginning of a Bobux size, they’ll have around 14mm of space between their foot and the end of the shoe, allowing them 7mm of growth and 7mm of wiggle room. Your child’s toes should never be touching the end of the shoe. As you can see the Xplorer, Step Up and I-Walk ranges include size 22. This is because of the different developmental stages children can be at when wearing this size - some are walking confidently, others are still finding their feet!
