Please make sure to confirm the size before purchasing.Not every pair of shoes is in standard sizes.The inner length of the shoes is measured manually, and there may be a reasonable error of about 0.5cm Regarding the selection of children's shoe sizes, please note the following: Most children's shoe sizes are based on manufacturer's standards and do not have a unified standard (different shoes of the same size may have different dimensions). Please measure the foot length. For summer models, it is recommended that foot length + 0.5cm = shoe inner length. For spring/autumn and winter models, it is recommended that foot length + 1cm = shoe inner length (the cm indicated after each size is the shoe's inner length) Size 22 inner length 14cm cm, size 23 inner length 14.5cm cm, size 24 inner length 15cm cm, size 25 inner length 15.5cm cm, size 26 inner length 16.2cm cm, size 27 inner length 16.8cm cm, size 28 inner length 17.4cm cm, size 29 inner length 18cm cm, size 30 inner length 18.5cm cm, size 31 inner length 19 cm, size 32 inner length 19.6 cm, size 33 inner length 20.3 cm, size 34 inner length 21 cm, size 35 inner length 21.6 cm, size 36 inner length 22.2 cm, size 37 inner length 22.9 cm 1
