IGOR Yogı Nautıco Borreguıto, Children's Full Fur Rain Boots, Snow Boots, Thermal Fur, Made in Spain, Waterproof

Hello, the insole measurements for the Igor Yogi Nautico Borreguito fur-lined boot model are as follows: Size 27: Insole length approximately 17.0–17.2 cm Size 28: Insole length approximately 17.7–18.0 cm Since the interior of the model is fully lined with thick thermal sheepskin (full borreguito), the interior volume is slightly narrower than that of standard shoes. Additionally, since these boots will be worn with thick socks during the winter months, we recommend leaving approximately 0.5–1 cm of wiggle/growth room to prevent your child’s foot from getting pinched at the front. For a net foot measurement of 17.1 cm, size 27 is right at the limit and may feel tight; therefore, we recommend choosing size 28 for a comfortable, relaxed fit and long-lasting use. We hope you enjoy your shopping experience.
