Our Purchase Recommendation for Children's Feet: When buying, plan for 1.2–1.7 cm of extra space beyond the foot length. This allows the foot enough room to roll and the shoe will accompany your child for a few months longer before the next size is needed. The values stated in the "Ideal Foot Length" column are based on KOEL's wearing recommendation of 0.6–1.2 cm of extra space – i.e., how the shoe should fit when first put on. Since children's feet grow quickly, we include the growth buffer directly in our purchase recommendation.
