Hello dear customer, we are sending you our size chart. 33-22 cm, 34-22.7 cm 35-23.3 cm, 36-24 cm, 37-24.6 cm, 38-25.3 cm, 39-26 cm, 40-26.7 cm, 41-27.4 cm, 42-28 cm, 43-28.7 cm, 44-29.4 cm, 45-30 cm, 46-30.7 cm, 47-31.4 cm, 48-32 cm. This table shows that the shoe size is corresponding to the foot length (measured from heel to the longest toe). To choose the correct size, you can measure your foot length and use the closest value in the table as a reference. We recommend you measure while standing with your foot firmly on the floor and measure in the evening hours because feet tend to swell slightly by the end of the day. This way, you can easily determine the size that suits you best.
